Detailed explanation-1: -The heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid. Due to this temperature difference, hot fluids tend to rise, whereas cold fluids tend to sink. This creates a current within the fluid called a convection current.

Detailed explanation-2: -Due to buoyancy, the less dense, hotter part of the fluid rises up. And the colder, denser fluid replaces it. This process is repeated when this part also gets heated and rises up to be replaced by the colder upper layer. This is how the heat is transferred through convection.

Detailed explanation-3: -Convective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water.

Detailed explanation-4: -In Liquids and gases, heat transfer takes place by convection. Heat transfer takes place by the process of radiation when there are no particles of any kind which can move and transfer heat.

Detailed explanation-5: -Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids.
