When a substance is heated or cooled, the temperature of the object will change, ΔT, according to the Specific Heat Capacity, c, of the substance, as well as the mass, M, of the substance and the amount of energy, Q, which is supplied.
When a substance undergoes a phase change, the temperature remains constant until the phase change is complete. The amount of energy required for the phase change depends on the mass of the substance and the Latent Heat of the substance, L.
This experiment simulates a idel caliorimetry experiment, where the caliorimetre doesn't loose heat to the environment.
Experimental Apparatus: Left - Caliorimeter with heating element from power supply
Centre - Power supply, providing 10 V at 1 Amp, Right- GLX measuring temperature
