Due to heat liquid film evaporates and vapors hit the condenser.

What is Convection - Convective Heat Transfer - Definition

May 22, 2019 In general, convection is either the mass transfer or the heat transfer due to bulk movement of molecules within fluids such as gases and liquids. Although liquids and gases are generally not very good conductors of heat, they can transfer heat quite rapidly by convection. Convection takes place through advection, diffusion or both.
