Which one of these thermometers is portable as well as simple to use?

1. Constant-volume gas thermometer
2. resistance thermometer
3. Thermocouple
4. Mercury-in-glass thermometer

The sensitivity 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 min and max temperatures that the thermometer can measure
4. None of the above

Thermometer that is best suited for measuring rapidly changing temperatures is

1. Constant-volume gas thermometer
2. resistance thermometer
3. Thermocouple
4. Mercury-in-glass thermometer

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
