​Conduction explains the process in which the transfer of heat takes place between objects by direct contact.

​

Convection refers to the form of heat transfer in which energy transition occurs within the fluid.

​

Radiation helps the heat to flow through empty spaces

​Conduction, energy flows through direct contact.

​Convection: the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
