Thermal properties and temperature

A student places a thermistor in series with a battery and an ammeter, then uses the thermistor’s resistance to work out the temperature.

The diagrams show four thermometers. Which thermometer has the highest sensitivity and which thermometer has the widest range?

May/June 2018

In many situations, a thermocouple is used rather than a liquid-in-glass thermometer to measure temperature. Which property of a thermocouple is a major advantage?

Water evaporating from the skin’s surface leads to cooling. If a refrigerator is turned on, the cooling coils at the top of the inside space become cold. A convection current is then produced, which cools the air inside the refrigerator.

A gas enclosed in a container is compressed by a piston while the temperature remains constant. Which property of the gas stays the same?

Oct/Nov 2024

A sample of a solid is heated until it changes into a liquid. During melting, which statement about the sample is correct?

Oct/Nov 2025

The diagram represents two changes of state, X and Y. Which row identifies the names of these two changes of state?

A laboratory bench holds an iron beaker that contains liquid X. Liquid X starts to evaporate gradually. The iron beaker containing liquid X is then placed on an induction heater, as shown in Fig. 5.1. Diagram labels: iron beaker, liquid X, induction heater, coil of wire. Fig. 5.2 shows the location of point P.
