1. Which one of the following is a correct statement about temperature?
a. It is a measure of how warm an object is.
b. It is a measure of how hot or cold an object is.
c. It is a measure of how heavy an object is.
d. None of these

2. In which of the following thermometers is a kink used?
a. Digital thermometers
b. Infra-red thermometers
c. Mercury-based thermometer
d. None of these

3. Which of the following in degree Celsius is equivalent to 32°F?
a. 100°C
b. 10°C
c. 0°C
d. 1°C

4. Sukanya and Diya measured their body temperatures. Sukanya found it to be 98.6°F, while Diya's body temp was 37°C. Which of the following statements is true?
a. Sukanya has a higher body temperature than Diya.
b. Diya has a lower body temperature than Sukanya.
c. Sukanya and Diya both have normal body temperature.
d. Sukanya is suffering from fever.

The answers to the questions are: 1) b, 2) c, 3) c, and 4) c. Temperature measures how hot or cold an object is, and Sukanya's and Diya's body temperatures are both normal. Mercury-based thermometers use a kink to retain the liquid, and 32°F equals 0°C.

Which one of the following is a correct statement about temperature? Temperature is a measure of how hot or cold an object is. It tells us about the thermal energy or heat content of an object. Therefore, the correct statement is:

b. It is a measure of how hot or cold an object.

In which of the following thermometers is a kink used? A kink is often found in liquid-in-glass thermometers, specifically mercury-based ones, to prevent the mercury from falling back into the bulb once it is withdrawn from the measured object. Therefore, the correct choice is:

c. Mercury-based thermometer

Which of the following in degree Celsius is equivalent to 32°F? To convert Fahrenheit to Celsius, we can use the formula:

C = 9 5 ​ ( F − 32 )
For 32°F:
C = 9 5 ​ ( 32 − 32 ) = 0° C
Therefore, the correct answer is:
c. 0°C

Sukanya and Diya measured their body temperatures. Sukanya found it to be 98.6°F, while Diya's body temp was 37°C. Which of the following statements is true? 98.6°F is equivalent to 37°C, which is considered the average normal body temperature for a healthy human. Therefore, both Sukanya and Diya have normal body temperature. The correct statement is:

c. Sukanya and Diya both have normal body temperature.
