  • 3. 

    Berikut benda yang dibakar akan menjadi abu yaitu ....

    • Batu

    • Besi

    • Kertas

    • Plastik

    Correct Answer
    A. Kertas
    Explanation
    When burned, paper undergoes combustion and is converted into ashes. This is because paper is primarily made up of cellulose, which is a complex organic compound. During combustion, the heat breaks down the cellulose molecules into simpler compounds, releasing carbon dioxide, water vapor, and other gases. The remaining solid residue is the ash, which is typically gray or white in color. Therefore, when paper is burned, it turns into ashes.

  • 4. 

    Lilin jika dinyalakan akan berubah dari ....

    • Padat menjadi gas

    • Padat menjadi cair

    • Cair menjadi padat

    • Gas menjadi cair

    Correct Answer
    A. Padat menjadi cair
    Explanation
    When a candle is lit, the heat from the flame melts the solid wax, causing it to change from a solid state to a liquid state. This is because the heat increases the kinetic energy of the wax molecules, causing them to move more freely and break away from their fixed positions in the solid structure. Therefore, the correct answer is "padat menjadi cair" which means "solid becomes liquid" in English.

    Rate this question:

  • 5. 

     Plastik jika dibakar akan ....

    • Membeku

    • Meleleh

    • Mengeras

    • Melapuk

    Correct Answer
    A. Meleleh
    Explanation
    When plastic is burned, it undergoes a process called melting. This is because the heat causes the plastic molecules to break apart and become a liquid. Therefore, the correct answer is "meleleh".

    Rate this question:

  • 6. 

    Buah yang busuk bisa dilihat dari ....

    • Baunya

    • Daunnya

    • Batangnya

    • Bunganya

    Correct Answer
    A. Baunya
    Explanation
    The correct answer is "baunya" because when a fruit is rotten, it emits a foul smell. By using our sense of smell, we can easily identify if a fruit is spoiled or not. Therefore, the smell of the fruit is a reliable indicator of its freshness or decay.

    Rate this question:

  • 7. 

    Kayu jika terkena air secara terus-menerus akan ....

    • Menjadi kuat

    • Menjadi lapuk

    • Tahan lama

    • Mudah terbakar

    Correct Answer
    A. Menjadi lapuk
    Explanation
    When wood is continuously exposed to water, it absorbs the moisture, which leads to the growth of fungi and bacteria. These microorganisms break down the wood fibers, causing it to decay and become soft and crumbly. This process is known as wood rot or wood decay, which ultimately results in the wood becoming "lapuk" or rotten.

    Rate this question:

  • 8. 

    Air bila dipanaskan akan ....

    • Mengembun

    • Membeku

    • Menguap

    • Mencair

    Correct Answer
    A. Menguap
    Explanation
    When air is heated, it undergoes a process called evaporation or vaporization, where it changes from a liquid state to a gas state. This is why the correct answer is "menguap", which means "to evaporate" in English.

    Rate this question:

  • 9. 

    Benda yang tidak meleleh ketika dipanaskan adalah ....

    • Kayu

    • Mentega

    • Cokelat batang

    • Margarin

    Correct Answer
    A. Kayu
    Explanation
    Kayu tidak meleleh ketika dipanaskan karena memiliki struktur yang sangat padat dan kuat. Kayu terdiri dari serat-serat yang saling terikat erat, sehingga membutuhkan suhu yang sangat tinggi untuk dapat melelehkannya. Selain itu, kayu juga mengandung sedikit air dan minyak, yang membuatnya lebih tahan terhadap panas. Hal ini menjadikan kayu sebagai bahan yang ideal untuk berbagai keperluan konstruksi dan pembuatan perabotan.

  • 10. 

    Baju jika sering terkena sinar matahari bisa menjadi kusam, maka yang berubah ....

    • Wujudnya

    • Ukurannya

    • Warnanya

    • Bahannya

    Correct Answer
    A. Warnanya
    Explanation
    When clothes are exposed to sunlight frequently, their color can become dull or faded. Therefore, the thing that changes in this situation is the color of the clothes.

    Rate this question:

  • 11. 

    Perubahan yang dapat kembali ke wujud asal adalah ....

    • Air menjadi es

    • Beras menjadi nasi

    • Kayu menjadi arang

    • Besi menjadi karat

    Correct Answer
    A. Air menjadi es
    Explanation
    When water freezes, it undergoes a physical change and transforms into ice. This change is reversible, as ice can melt back into water when heated. Therefore, the transformation of water into ice is a change that can return to its original form.

    Rate this question:

  • 12. 

    Besi yang  berkarat akan  ....

    • Semakin kuat

    • Memendek

    • Menjadi hitam

    • Keropos

    Correct Answer
    A. Keropos
    Explanation
    When iron rusts, it undergoes a chemical reaction with oxygen in the presence of moisture. This reaction causes the iron to corrode and weaken, resulting in the formation of rust. Over time, the rust will eat away at the iron, causing it to become porous and brittle. Therefore, the correct answer is "keropos" which means porous or corroded.

    Rate this question:

  • 13. 

    Sayur jika dibiarkan akan menjadi basi. Penyebab perubahannya adalah ....

    • Panas api

    • Pemanasan

    • Suhu udara

    • Bakteri pembusuk

    Correct Answer
    A. Bakteri pembusuk
    Explanation
    Sayur jika dibiarkan akan menjadi basi karena adanya bakteri pembusuk. Bakteri ini akan memecah bahan organik dalam sayur menjadi senyawa yang berbau tidak sedap dan merusak kualitas sayur. Proses pembusukan ini terjadi ketika sayur terpapar udara dan kelembaban yang tinggi, yang memberikan lingkungan yang ideal bagi pertumbuhan bakteri pembusuk. Bakteri pembusuk akan menghasilkan enzim yang merusak sel-sel sayur dan mengubahnya menjadi bahan yang tidak layak konsumsi.

    Rate this question:

  • 14. 

    Daging direbus menjadi lunak, penyebabnya adalah ....

    • Pembakaran

    • Pencucian

    • Pemanasan

    • Pembersihan

    Correct Answer
    A. Pemanasan
    Explanation
    The correct answer is "pemanasan" because boiling meat makes it tender. The process of boiling involves heating the meat in water or other liquid until it reaches a high temperature, which helps to break down the proteins and connective tissues in the meat, resulting in a softer texture.

    Rate this question:

  • 15. 

    Rel kereta api jika terkena panas akan ....   

    • Mencair

    • Membeku

    • Mengeras

    • Memuai

    Correct Answer
    A. Memuai
    Explanation
    When a railway track is exposed to heat, it expands due to the expansion of the metal. This is known as thermal expansion. As a result, the correct answer is "memuai" which means "to expand" in English.

    Rate this question:

  • 16. 

    Benda yang mengeras jika terbakar adalah ....

    • Tanah liat

    • Besi

    • Kayu

    • Plastik

    Correct Answer
    A. Tanah liat
    Explanation
    Tanah liat mengeras jika terbakar karena proses pembakaran akan menghilangkan air yang terkandung dalam tanah liat, sehingga menyebabkan partikel-partikel tanah liat saling berikatan dan membentuk struktur yang lebih padat dan keras.

    Rate this question:

  • 17. 

    Kayu menjadi keropos akibat ....

    • Pengasapan 

    • Pembakaran

    • Pemanasan

    • Pelapukan

    Correct Answer
    A. Pelapukan
    Explanation
    Kayu menjadi keropos akibat pelapukan. Pelapukan adalah proses alami di mana bahan organik seperti kayu terurai secara perlahan oleh faktor-faktor seperti air, udara, dan mikroorganisme. Proses pelapukan ini menyebabkan kayu menjadi rapuh dan keropos seiring berjalannya waktu. Pengasapan, pembakaran, dan pemanasan tidak menyebabkan kayu menjadi keropos, tetapi dapat merusak atau mengubah sifat kayu.

    Rate this question:

  • 18. 

    Berikut ini yang bukan merupakan perubahan benda yaitu ....

    • Es mencair

    • Ban dipompa

    • Buah membusuk

    • Kayu dibakar

    Correct Answer
    A. Ban dipompa
    Explanation
    Ban dipompa bukan merupakan perubahan benda karena proses pemompaan hanya mengubah keadaan ban dari kempis menjadi kembung, tetapi tidak mengubah sifat, bentuk, atau komposisi bahan ban itu sendiri.

    Rate this question:

  • 19. 

    Berikut ini merupakan sifat benda padat jika dipindah-pindah, kecuali  ....

    • Bentuknya tetap

    • Warnanya tetap

    • Ukurannya berubah

    • Mudah dipegang

    Correct Answer
    A. Ukurannya berubah
    Explanation
    The given options describe the properties of solid objects when they are moved. The options "bentuknya tetap" (shape remains the same), "warnanya tetap" (color remains the same), and "mudah dipegang" (easy to hold) are all correct properties of solid objects when they are moved. However, the option "ukurannya berubah" (size changes) is incorrect because the size of a solid object does not change when it is moved.

    Rate this question:

  • 20. 

    Berikut ini perubahan kayu dibakar, kecuali ....

    • Arang

    • Abu

    • Asap

    • Api

    Correct Answer
    A. Api
    Explanation
    The given options are all related to the burning of wood, except for "api" which means fire. Fire is not a physical change that occurs to wood, but rather the result of the burning process. The other options - arang (charcoal), abu (ash), and asap (smoke) - are all byproducts or remnants of wood burning.

    Rate this question:

  • 21. 

    Besi di tempat terbuka dapat berkarat akibat  ....

    • Panas matahari

    • Tiupan angin

    • Air hujan

    • Bakteri pembusuk

    Correct Answer
    A. Air hujan
    Explanation
    Besi di tempat terbuka dapat berkarat akibat air hujan. Air hujan mengandung oksigen dan air, yang merupakan faktor utama dalam terjadinya proses oksidasi pada besi. Oksidasi ini menyebabkan besi bereaksi dengan oksigen dan membentuk karat. Jadi, air hujan dapat menyebabkan besi berkarat jika terpapar dalam jangka waktu yang cukup lama.

    Rate this question:

  • 22. 

    Rel  kereta api dipasang saling renggang supaya ....

    • Tidak melengkung waktu kepanasan

    • Agar kereta api tidak keluar rel

    • Supaya rel mudah dipasang

    • Agar sambungan tidak patah

    Correct Answer
    A. Tidak melengkung waktu kepanasan
    Explanation
    The correct answer is "tidak melengkung waktu kepanasan" because when the railway tracks are installed with gaps, it allows for expansion of the tracks due to heat. This prevents the tracks from bending or warping when they expand, ensuring that the train stays on the tracks and does not derail.

    Rate this question:

  • 23. 

    Besi jika dibakar akan berwarna ....

    • Hitam

    • Biru

    • Merah

    • Hijau

    Correct Answer
    A. Merah
    Explanation
    When iron is burned, it produces a red color. This is due to the emission of energy in the form of light. The specific wavelengths of light emitted by burning iron correspond to the color red.

    Rate this question:

  • 24. 

     Berikut ini sifat benda cair jika dipindah-pindah, kecuali ....

    • Bentuknya berubah

    • Warnanya tetap

    • Ukurannya berubah

    • Susah dipegang

    Correct Answer
    A. Susah dipegang
    Explanation
    The given options describe the characteristics of a liquid when it is moved or transferred. The first option states that the shape of the liquid changes, which is true as liquids take the shape of the container they are in. The second option mentions that the color of the liquid remains the same, which is also true as the color of a liquid is not affected by its movement. The third option states that the size of the liquid changes, which is true as liquids can expand or contract when heated or cooled. The last option, "susah dipegang" (difficult to hold), does not accurately describe a characteristic of a liquid when it is moved.

    Rate this question:

  • 25. 

     Kayu jika dibakar akan berubah menjadi ....

    • Karat

    • Lunak

    • Arang

    • Cair

    Correct Answer
    A. Karat
    Explanation
    When wood is burned, it turns into charcoal. The word "karat" means rust in Indonesian, which is not a correct transformation of wood when it is burned. Therefore, the correct answer is "arang" which means charcoal in Indonesian.
