Question

How much of heat energy is required to raise the temperature of unit mass of materials by one degree centigrade

Answer 1

The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). The specific heat capacity of water is 4,200 joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.

Answer 2

It depends on the heat capacity of the substance. The "heat capacity" of asystem characterizes how much energymust be added to that system to raise itstemperature by 1 K (equal to a 1° Cchange). It's a measure of how manyways of "storing" internal energy are available to a system.
