How is heat transfer related to temperature
WebConvection: Convection is the transfer of heat from a surface by means of a fluid such as air. Natural convection occurs as air is heated: it expands, rises, and is replaced by cooler air. The amount of convection may be increased by using a fan to increase the flow of air. WebHeat transfer can be defined as the process of transfer of heat from an object at a higher temperature to another object at a lower temperature. Therefore heat is the measure of kinetic energy possessed by the particles in a given system. When the temperature of a system increases then its kinetic energy of the particles will also increase.
