Heat

Heat

Heat is the condition or quality of being hot or cold. In other words, the degree of hotness or coldness of a body or environment is termed as heat.

In physics, heat is a form of energy associated with the motion of atoms or molecules and capable of being transmitted through solid and fluid media by conduction, through fluid media by convection, and through empty space by radiation. The higher the temperature of a material, the faster the atoms are moving, and hence the greater the amount of energy present as heat.
