Specific heat capacity

When heat is supplied to a material, the particles that make up the material increases the speed of their motion. In a solid, the vibration of the particles becomes faster. In liquid, the particles move faster. As a result, the temperature of the material increases.

The amount of heat supplied and the increase in temperature is related by

Q=mc\Delta \theta

where Q  is the heat supplied, m  is the mass of the substance, c  is the specific heat capacity and \Delta \theta   is the change in temperature.

The specific heat capacity of a substance is defined as

The energy needed to increase the temperature of a substance by 1ºC is the specific heat capacity of the substance.
