Write the expression for the heat energy Q received by m kg of a substance of specific heat capacity c J kg^-1K^-1 when it is heated through △ t^oC.

Solution:

The movement of microscopic particles called atoms, molecules, or ions in solids, liquids, and gases produces heat energy. It is possible to transmit heat energy from one thing to another. Heat is the transfer or movement of energy caused by a temperature differential between two objects.

The expression for the heat energy Q is Q = c m △t (in joule)
