Keadaan panas atau dinginnya sebuah benda disebut ...
- A.
Termometer
- B.
Suhu
- C.
Derajat
- D.
Celcius
Correct Answer
B. SuhuExplanation
The correct answer is suhu. Suhu refers to the hotness or coldness of an object. It is a measure of the average kinetic energy of the particles in a substance. Termometer is a device used to measure temperature. Derajat means degrees, and Celcius is a unit of temperature measurement.Rate this question:

Suhu suatu benda diukur menggunakan ....
- A.
Barometer
- B.
Termometer
- C.
Higrometer
- D.
Manometer
Correct Answer
B. TermometerExplanation
A thermometer is used to measure temperature, which is the degree of hotness or coldness of an object or environment. Therefore, it is the most suitable instrument for measuring the temperature of an object. A barometer measures atmospheric pressure, a hygrometer measures humidity, and a manometer measures pressure of gases or liquids.Rate this question:

Prinsip kerja termometer adalah ... .
- A.
Pemuaian panjang kaca
- B.
Pemuaian volume kaca
- C.
Pemuaian panjang air raksa
- D.
Pemuaian volume air raksa
Correct Answer
D. Pemuaian volume air raksaExplanation
The correct answer is "pemuaian volume air raksa." The principle of a thermometer is based on the expansion of the volume of the liquid inside it, which in this case is mercury. As the temperature increases, the volume of the mercury expands, causing it to rise in the thermometer. Therefore, the principle of a thermometer is the expansion of the volume of mercury.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 kiri terasa dingin
Correct Answer
B. Tangan kanan dan kiri terasa hangatExplanation
When the right hand is exposed to hot water and the left hand is exposed to cold water, the temperature receptors in both hands send signals to the brain indicating the respective temperatures. However, when both hands are simultaneously exposed to lukewarm water, the brain receives mixed signals from the temperature receptors. As a result, the brain interprets the mixed signals as both hands feeling warm. Therefore, the correct statement is that both the right and left hands feel warm.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 the Celsius (C) and Fahrenheit (F) scales. It shows that the ratio between the Celsius scale and the Fahrenheit scale is (F-32) : 5 : 9, indicating that to convert from Celsius to Fahrenheit, you need to subtract 32 from the Fahrenheit temperature and then multiply it by 5/9.Rate this question:

Suhu 100 derajat celcius sama dengan ... .
- A.
60 derajat reamur
- B.
212 derajat fahrenheit
- C.
273 K
- D.
0 K
Correct Answer
B. 212 derajat fahrenheitExplanation
The correct answer is 212 degrees Fahrenheit. This is because 100 degrees Celsius is equal to 212 degrees Fahrenheit according to the conversion formula.Rate this question:

Suhu benda 40 derajat celsius sama dengan .....
- A.
24 derajat reamur
- B.
32 derajat reamur
- C.
48 derajat reamur
- D.
50 derajat reamur
Correct Answer
B. 32 derajat reamurExplanation
The correct answer is 32 degrees Reamur. This is because the conversion formula from Celsius to Reamur is R = C × 4/5. Therefore, when the temperature is 40 degrees Celsius, it can be converted to Reamur by multiplying it by 4/5, which equals 32 degrees Reamur.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 derajat celsius
- B.
Warnanya mengkilap
- C.
Tidak membasahi dinding kaca
- D.
Seperti menyesuaikan suhu disekitarnya
Correct Answer
A. Dapat digunakan untuk mengukur suhu di bawah -40 derajat celsiusExplanation
Air raksa memiliki kelebihan dibandingkan dengan alkohol jika digunakan untuk termometer, seperti warnanya yang mengkilap dan tidak membasahi dinding kaca. Namun, air raksa tidak dapat digunakan untuk mengukur suhu di bawah -40 derajat Celsius.Rate this question:

Bahan zat cair yang digunakan untuk termometer maksimum-minimum adalah ... .
- A.
Air raksa dan alkohol
- B.
Air raksa dan spiritus
- C.
Alkohol dan ethanol
- D.
Alkohol dan bimetal
Correct Answer
A. Air raksa dan alkoholExplanation
The correct answer is air raksa dan alkohol. Air raksa and alkohol are used as the liquid substances in a maximum-minimum thermometer. Air raksa is used to measure the maximum temperature, as it expands when heated. Alkohol is used to measure the minimum temperature, as it contracts when cooled. By using both substances, the thermometer can accurately measure and display both the highest and lowest temperatures reached.Rate this question:
