Measure Thermal Energy

Different materials need different amounts of heat to produce similar changes in their temperatures. The materials have different specific heats.

Land heats up and cools down faster than water.

Specific Heat is the amount of heat required to raise the temperature of 1 kg of a material by one degree (C or K)

1)Cp water=4184J/kgC
2)Cp sand=664J/kgC
