The specific heat capacity is the amount of thermal energy required to raise the temperature of one gram of a substance by one degree Celsius.

It is a characteristic property that gives the precise capacity of a substance to absorb or release heat. Its symbol is |c.|

Corps

In other words, the specific heat capacity is the amount of heat that one gram of a substance must absorb for its temperature to rise by one degree Celsius. It can also be the amount of heat that one gram of this substance must lose for its temperature to drop by one degree Celsius.

The following table lists the specific heat capacity of various elements, measured under standard conditions at SATP (standard ambient temperature and pressure), that is to say, at |25^\circ\text{C}| and |101.3\ \text{kPa}.|
