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
