Thermal properties and temperature — practice question
A thermocouple is a device that functions as a thermometer.
Fig. 4.1 shows a beaker containing molten sulfur whose initial temperature is above $400\,^{\circ}\text{C}$.
(a(i))[4]
On Fig. 4.1, sketch and label a thermocouple diagram that is used to find the temperature of the sulfur as it cools to room temperature.
(a(ii))[2]
Briefly describe how the temperature of the sulfur in the beaker is found.
(b)[1]
State one advantage of using a thermocouple to measure temperature instead of using a liquid-in-glass thermometer.
