Meaning of Specific Heat

What is Specific Heat:

Specific heat is known as physical quantity that expresses the amount of heat required by a substance per unit mass for its temperature to increase by one unittemperature that is usually measured in degrees Celsius.

As such, the specific heat is an intensive property of mattersince its value is representative of each substance or material, each of which, in turn, has different values ​​according to the state in which it is found (liquid, solid or gaseous).

For example, the specific heat of water is higher than any other substance: 1 calorie/gram °C (calorie per gram per degree Celsius). In this sense, the specific heat of water is greater than that of all metals.

The greater the specific heat of a substance, the more heat energy is required to increase its temperature. For this reason, more heat energy is required to heat water than to heat lead, whose specific heat is 0.031 calorie/gram °C.

The specific heat formula is c = C/mwhere c represents the specific heat of the substance, C the heat capacity and m its mass. So to obtain the specific heat it is necessary to divide the thermal capacity by the mass.
