State the size and unit of 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.
Explain how Fig. 2.2 shows that platinum is a suitable metal for use in a resistance thermometer.
Suggest a reason why a platinum resistance thermometer is not suitable for measuring a rapidly changing temperature.
Suggest a type of thermometer that is suitable for measuring a rapidly changing temperature.
A negative temperature coefficient thermistor may be used as a type of resistance thermometer. State one way in which the variation with temperature of the resistance of a thermistor differs from that of a platinum wire.
