Can we measure the temperature of solids using a laboratory thermometer? If not then which thermometer is used to measure the temperature of solids?
Since a thermometer can only measure the temperature in a small area, measuring the temperature of a solid directly is difficult. Powders or granular solids can be stirred at a very high rate and can be treated in the same manner as liquids, but it is difficult to feel confident in the observed temperature. For bulk solid materials (like a metal cube), the temperature is measured indirectly by performing a calorimetry experiment. To heat a solid to a desired temperature, place the solid in a liquid or solution heated to the desired temperature and allow the system to reach thermal equilibrium (when the liquid or solution is the same temperature as the solid). Thermal equilibrium is observed when the temperature of the system does not change for several minutes. |
