Sample questions

1. What is the instrument used to measure temperature?

   1. Thermometer
   2. Barometer
   3. Anemometer
   4. Hygrometer
   Show answer

   Answer: A. Thermometer

   A thermometer is the instrument used to measure temperature. It consists of a sealed tube containing a liquid, usually mercury or alcohol, which expands and contracts with temperature changes.

2. What is the boiling point of water on the Celsius scale?

   1. 0°C
   2. 100°C
   3. 212°F
   4. 273°C
   Show answer

   Answer: B. 100°C

   On the Celsius scale, water boils at 100 degrees Celsius.

3. If the temperature is -40 degrees, which scale is it the same in both Celsius and Fahrenheit?

   1. Celsius
   2. Fahrenheit
   3. Both
   4. Neither
   Show answer

   Answer: C. Both

   -40 degrees is the same temperature in both Celsius and Fahrenheit scales.

4. Which of the following is a compound thermometer?

   1. Mercury thermometer
   2. Alcohol thermometer
   3. Bimetallic thermometer
   4. Infrared thermometer
   Show answer

   Answer: C. Bimetallic thermometer

   A bimetallic thermometer is a compound thermometer that uses two different metals bonded together that expand at different rates.

5. Which device helps to convert temperature into an electrical signal?

   1. Thermocouple
   2. Bimetal strip
   3. Mercury thermometer
   4. Anemometer
   Show answer

   Answer: A. Thermocouple

   A thermocouple consists of two different types of metals joined at one end and produces a voltage that corresponds to temperature.
