State the magnitude and unit that correspond to absolute zero on the thermodynamic temperature scale.
Explain why a temperature reading from a laboratory liquid-in-glass thermometer is not a measurement of thermodynamic temperature.
Fig. 2.1 presents a simplified diagram of a thermometer known as a platinum resistance thermometer. The glass tube is dipped into the surroundings whose temperature is to be found. The resistance between terminals $X$ and $Y$ is measured. Fig. 2.2 illustrates how the resistivity $\rho$ of platinum changes with thermodynamic temperature $T$.
Explain how Fig. 2.2 shows that platinum is a suitable metal to use in a resistance thermometer.
Suggest a reason why a platinum resistance thermometer is not suitable for measuring a temperature that changes rapidly.
Suggest a type of thermometer that is suitable for measuring a temperature that changes rapidly.
A negative temperature coefficient thermistor may be used as a resistance thermometer. State one way in which the variation of resistance with temperature in a thermistor differs from that in a platinum wire.
