Orang yang sehat akan mempunyai suhu tubuh rata-rata ... .
- A.
27° C
- B.
35° C
- C.
37° C
- D.
40° C
Correct Answer
C. 37° CExplanation
The average body temperature of a healthy person is 37° C. This temperature is considered normal for adults and is an indication of a balanced and healthy body. It is important to note that body temperature can vary slightly from person to person, but 37° C is generally accepted as the standard.Rate this question:

Termometer klinis skalanya mempunyai batas bawah dan batas atas... .
- A.
20 ° C – 50 ° C
- B.
30 ° C – 40 ° C
- C.
35 ° C – 42 ° C
- D.
35 ° C – 45° C
Correct Answer
C. 35 ° C – 42 ° CExplanation
The correct answer is 35 ° C – 42 ° C. This is because a clinical thermometer is designed to measure the human body temperature, which typically falls within the range of 35 ° C to 42 ° C. The lower limit of 35 ° C ensures that temperatures below normal body temperature can be accurately measured, while the upper limit of 42 ° C allows for the measurement of fevers, which are commonly within this range.Rate this question:

Yang digunakan untuk titik tetap atas termometer fahrenheit adalah ...
- A.
Es yang sedang mencair diberi angka nol
- B.
Air yang sedang mendidih diberi angka 100
- C.
Es yang sedang mencair diberi angka 32
- D.
Air yang sedang mendidih diberi angka 212
Correct Answer
D. Air yang sedang mendidih diberi angka 212Explanation
The correct answer is that water boiling is given the number 212 on the Fahrenheit thermometer. This is because the Fahrenheit scale was developed by Daniel Gabriel Fahrenheit, who set the freezing point of water at 32 degrees and the boiling point at 212 degrees.Rate this question:

Perbandingan skala termometer berikut ini yang benar adalah ... .
- A.
C : R = 4 : 5
- B.
C : F = 5 : 9
- C.
R : F = 9 : 4
- D.
C : (F-32) : 5 : 9
Correct Answer
D. C : (F-32) : 5 : 9Explanation
The correct answer is C : (F-32) : 5 : 9. This is the correct comparison of scales for the thermometer. It shows the relationship between Celsius (C), Fahrenheit (F), and the difference between Fahrenheit and 32. The ratio 5:9 represents the conversion from Celsius to Fahrenheit, where for every 5 degrees Celsius, there are 9 degrees Fahrenheit. The inclusion of (F-32) indicates the adjustment needed to convert Fahrenheit to Celsius.Rate this question:

Kelebihan air raksa dibandingkan dengan alkohol jika digunakan untuk termometer adalah sebagai berikut, kecuali ... .
- A.
Dapat digunakan untuk mengukur suhu di bawah - 40° C
- B.
Warnanya mengkilap
- C.
Tidak membasahi dinding kaca
- D.
Cepat menyesuaikan suhu disekitarnya
Correct Answer
A. Dapat digunakan untuk mengukur suhu di bawah - 40° CExplanation
Air raksa memiliki kelebihan dibandingkan dengan alkohol jika digunakan untuk termometer, seperti warnanya yang mengkilap, tidak membasahi dinding kaca, dan cepat menyesuaikan suhu disekitarnya. Namun, air raksa tidak dapat digunakan untuk mengukur suhu di bawah -40° C.Rate this question:

Prinsip kerja termometer raksa adalah ... .
- A.
Pemuaian panjang kaca
- B.
Pemuaian volume kaca
- C.
Pemuaian panjang raksa
- D.
Pemuaian volume raksa
Correct Answer
D. Pemuaian volume raksaExplanation
The correct answer is "pemuaian volume raksa". Mercury thermometers work based on the expansion of mercury volume. As the temperature increases, the volume of mercury inside the thermometer expands, causing the level of mercury to rise in the glass tube. This expansion and contraction of mercury volume are used to measure and indicate changes in temperature.Rate this question:

Pada percobaan tangan kanan masuk ke air panas dan tangan kiri masuk ke air dingin. Ketika kedua tangan dimasukkan secara bersamaan ke air biasa, peryataan yang benar adalah ... .
- A.
Tangan kanan dan kiri terasa dingin
- B.
Tangan kanan dan kiri terasa hangat
- C.
Tangan kiri terasa dingin dan tangan kanan hangat
- D.
Tangan kiri terasa hangat dan tangan kanan terasa dingin
Correct Answer
C. Tangan kiri terasa dingin dan tangan kanan hangatExplanation
When the right hand is immersed in hot water and the left hand is immersed in cold water, the temperature receptors in each hand adapt to the respective temperatures. When both hands are simultaneously immersed in room temperature water, the temperature receptors in the left hand, which have adapted to the cold temperature, will perceive the room temperature water as cold. On the other hand, the temperature receptors in the right hand, which have adapted to the hot temperature, will perceive the room temperature water as warm. Therefore, the correct statement is that the left hand feels cold and the right hand feels warm.Rate this question:

Pernyataan tentang indera peraba berikut ini benar, kecuali ... .
- A.
Tangan dapat digunakan untuk mengukur suhu karena dapat merasakan panas dan dingin
- B.
Pengukuran suhu dengan tangan sangat tepat karena berdasarkan perasaan
- C.
Tangan dapat merasakan suhu sangat dingin dan suhu sangat panas
- D.
Indera peraba kurang cepat menyesuaikan dengan suhu lingkungan
Correct Answer
B. Pengukuran suhu dengan tangan sangat tepat karena berdasarkan perasaanExplanation
The statement "pengukuran suhu dengan tangan sangat tepat karena berdasarkan perasaan" is incorrect. This is because the sense of touch is subjective and can vary from person to person. It is not a precise or accurate method of measuring temperature.Rate this question:

Satuan suhu dalam Sistem Internasional (SI) adalah ... .
- A.
Kelvin
- B.
Celcius
- C.
Reamur
- D.
Fahrenheit
Correct Answer
A. KelvinExplanation
The correct answer is kelvin. Kelvin is the unit of temperature in the International System of Units (SI). It is the base unit of temperature and is defined as 1/273.16 of the triple point of water. Unlike Celsius and Fahrenheit, Kelvin does not use negative values for temperatures below freezing point. It is commonly used in scientific and engineering calculations where absolute temperature is required.Rate this question:

Keadaan panas atau dinginnya sebuah benda disebut ...
- A.
Kalor
- B.
Suhu
- C.
Derajat
- D.
Celcius
Correct Answer
B. SuhuExplanation
The correct answer is "suhu". Suhu refers to the level of hotness or coldness of an object. It is a measurement of the average kinetic energy of the particles in the object. Suhu is typically measured using a thermometer and can be expressed in various scales such as Celsius, Fahrenheit, or Kelvin. Kalor refers to heat energy, derajat means degrees, and Celsius is a unit of measurement for temperature on the Celsius scale.Rate this question:
