Specific Heat Capacity - Fridge Physics

Specific heat capacity is how much heat energy is required to raise 1 kg of a substance by 1 °C.

What is Specific heat capacity?

Specific heat capacity is how much heat energy is required to raise 1 kg of a substance by 1 °C. Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass. The specific heat capacity of a material is a physical property and different materials have a different specific heat capacities.

Specific heat capacity equation

To calculate Specific heat capacity we write the equation like this.

$\Delta E = mc\Delta\theta$
