Heat transfer is the exchange of thermal energy between physical systems, depending on the temperature and pressure, by dissipating heat.The fundamental modes of heat transfer are conduction or diffusion, convection and radiation.eat transfer is the exchange of thermal energy between physical systems, depending on the temperature and pressure, by dissipating heat.
Because of convection! There are three types of heat transfer: conduction, convection and radiation. Convection is a type of heat transfer that can only happen in liquids and gases, because it involves those liquids or gases physically moving. Convection happens when there is a difference in temperature between two parts of a liquid or gas. The hot part of a fluid rises, and the cooler part sinks. But let's use an example to think about why it happens, lest we assume that the fluid has a mind of its own.
