Heat is transferred through material by three main processes: conduction, convection, and radiation.

1. Conduction: This is the process of heat transfer from one particle of matter to another without the movement of the particles themselves. It occurs mainly in solids. For example, when one end of a metal rod is heated, the heat is transferred from the hot end to the cooler end through conduction.

2. Convection: This is the process of heat transfer by the actual movement of the heated particles of a gas or liquid. It occurs mainly in fluids. For example, when a pot of water is heated, the water at the bottom of the pot gets heated first. The heated water rises to the top, and the cooler water at the top moves down to be heated. This cycle continues until all the water is heated.

3. Radiation: This is the process of heat transfer in which energy is transferred in the form of electromagnetic waves. It does not require any medium (solid, liquid, or gas) for the transfer. For example, the heat from the sun reaches the earth through radiation.

In all these processes, heat is transferred from a region of higher temperature to a region of lower temperature.
