In the conduction mode of transference of heat, the molecules of solid pass heat from one molecule to another without moving from their positions.

The amount of heat required to raise the temperature of a substance is called is specific heat capacity.

The process of heat transfer in liquids and gases is through convection mode.

The process of heat transfer from a body at higher temperature to a body at lower temperature without heating the space between them is known as radiation.
