 Heat is a form of energy associated with the motion of atoms and molecules in a substance. It is a transferable quantity that flows from one system or object to another due to a temperature difference. The direction of heat transfer is always from a region of higher temperature to a region of lower temperature. The primary ways in which heat can be transferred are: Conduction: This is the transfer of heat through direct contact between particles of a substance. In materials, heat is conducted when vibrating particles pass on their energy to neighboring particles. Metals, for example, are good conductors of heat. Convection: Convection involves the transfer of heat through the movement of fluids (liquids or gases). As a fluid is heated, it becomes less dense and rises, creating a flow. This can be seen in processes like boiling water or the movement of air in a room. Radiation: Radiation is the transfer of heat through electromagnetic waves, such as infrared radiation. Unlike co...
