Physics > Specific Heat Capacities

Specific heat capacity, also known simply as specific heat, is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by a certain temperature interval. The symbols for specific heat capacity are either C or c depending on how the quantity of a substance is measured.

Specific heat capacity is measured in units of joules per kilogram per degree (J.kg-1.K-1). The heat capacity of an object, taken as a whole, is simply given as J.K-1

The table below shows some standard specific heat capacities:

Ice 2100
Ethanol 2400
Copper 390
Aluminium 900
Glass 840
Mercury 140
Wood 1700
Lead 130
