Soal IPA Materi Suhu Dan Termometer

Explanation
The given statement is true. Suhu refers to the level or degree of heat of an object. It is a measure of the average kinetic energy of the particles in the object. Temperature is commonly measured using units such as Celsius, Fahrenheit, or Kelvin. Therefore, suhu does represent the level of heat in a body.

Explanation
The question is asking about the temperature scale that has a lower fixed point at 273 and an upper fixed point at 373. The correct answer is Kelvin because the Kelvin scale is an absolute temperature scale where 0 Kelvin represents absolute zero, the point at which all molecular motion ceases. The Kelvin scale is commonly used in scientific and engineering applications where precise temperature measurements are required.

Explanation
The explanation for the correct answer, Fahrenheit, is that the given temperature range of 32o to 212o corresponds to the Fahrenheit scale. In this scale, 32o represents the freezing point of water and 212o represents the boiling point of water at standard atmospheric pressure. Therefore, the Fahrenheit scale is the appropriate scale for the given temperature range.

Explanation
Alkohol sering digunakan sebagai pengisi termometer karena memiliki sifat yang mengembang dengan cepat ketika dipanaskan. Selain itu, alkohol juga memiliki titik didih yang rendah, sehingga dapat digunakan untuk mengukur suhu yang lebih tinggi daripada air. Minyak goreng dan sirup mungkin tidak cocok sebagai pengisi termometer karena titik didihnya yang lebih tinggi daripada air. Air sendiri juga bisa digunakan sebagai pengisi termometer, tetapi alkohol lebih umum digunakan karena sifat-sifatnya yang lebih sesuai untuk pengukuran suhu.

Explanation
The statement in the question is incorrect. The correct statement should be "Semakin cepat getaran partikel-partikel benda, berarti suhu benda semakin tinggi" which translates to "The faster the vibration of particles in an object, the higher the temperature of the object." Therefore, the correct answer is False.

Explanation
The statement explains that sensory perception is not a reliable measure of heat levels because it provides qualitative temperature measurements that cannot be used as a reference. This implies that relying solely on our senses to determine the temperature may not be accurate or consistent, emphasizing the need for more objective and quantitative methods of measurement. Therefore, the correct answer is true, as it aligns with the explanation provided.

Explanation
Raksa dapat digunakan sebagai pengisi termometer karena memiliki keistimewaan warna mengkilap dan cepat bereaksi terhadap perubahan suhu. Ini berarti raksa akan dengan cepat menunjukkan perubahan suhu yang terjadi dengan perubahan dalam panjang kolom raksa dalam termometer. Warna mengkilap juga memudahkan pengguna untuk membaca suhu yang ditunjukkan oleh termometer.

Explanation
In the Reamur scale, 60 degrees is equivalent to 75 degrees in the Celsius scale. This means that if the temperature is 60 degrees on the Reamur scale, it would be 75 degrees on the Celsius scale.

Explanation
40 degrees Celsius is equal to 104 degrees Fahrenheit. This conversion can be done by using the formula: °F = (°C × 9/5) + 32. Plugging in the value of 40 for °C, we get (40 × 9/5) + 32 = 104 °F.

Explanation
The correct answer is Kelvin. Kelvin is the temperature scale used in the International System of Units (SI). It is based on absolute zero, the point at which all molecular motion ceases. The Kelvin scale has the same size units as the Celsius scale, but it starts at absolute zero, which is -273.15 degrees Celsius. The Kelvin scale is used in scientific and engineering fields where precise temperature measurements are required.
