Temperature is measured by thermometer on physical properties that change linearly with temperature to give temperature readings. Physical properties of a thermometer include;
ii) Expansion of a compound strip of two metals
iii) Thermoelectric property change in which when junction of two different metals are heated an electric current is generated
iv) Change of resistance of a wire e.g. platinum resistance thermometer
