Measurement of Temperature Quiz Questions & Answers PDF Download - 3

The responsiveness of a thermometer refers to

1. how quickly the thermometer can register change in temperature
2. the amount of change in thermometric property for a unit change in temperature
3. the minimum and maximum temperatures that the thermometer can measure
4. None of the above

A thermocouple shows an EMF of 5.00 mV with one of its junctions at 0 °C and the other at 100 °C. If the 100 °C junction is taken out of the boiling water and placed in a glass of water having temperature same as the room temperature (assume room temperature in this case = 25 °C), the EMF registered on thermocouple would be

1. 1.25 mV
2. 5 mV
3. 10 mV
4. 20 mV

Feature of the laboratory thermometer that makes it responsive is

1. The thin-walled glass bulb
2. The small bulb containing a small amount of liquid
3. The fine as well as uniform bore of the capillary tube
4. The relatively small size of the thermometer

Every temperature measuring instrument makes use of a physical property of a substance in order to measure temperature objectively, which physical property is used by Thermocouple?

1. Electromotive force
2. Volume of a fixed mass of liquid
3. resistance of a piece of metal
4. Pressure of a fixed mass of gas at constant volume

Feature of laboratory thermometer that makes it sensitive is

1. The thin-walled glass bulb
2. The small bulb containing a small amount of liquid
3. The fine as well as uniform bore of the capillary tube
4. The relatively small size of the thermometer
