Heat Capacities

Specific Heat Capacity Experiment

The specific heat capacity of a substance is the amount of energy needed to increase the temperature of 1 kg of that substance by 1°C.

Increasing internal energy of the body

The heater increases the internal energy of the body and we measure this using a joulemeter.

Measuring the body's temperature

Measure the temperature of the body (object) at the start and measure the maximum temperature of the body at the end.

Calculating specific heat capacity

Specific heat capacity = $\frac{change \;in\; internal\; energy}{mass \;(kg)\; {\times}\; maximum \;temperature\; rise\; (^oC)}$
