Hint: A heated body loses heat in three ways depending upon the conditions met. When two conductors are met, heat loss occurs through conduction. Heat Loss through Convection occurs when the hot body is placed in a cooler fluid. And through radiation, if the body is significantly hotter than its surrounding.

Heat loss is the loss of thermal energy as heat to the surrounding. A hotter loses its heat to a colder body or surrounding.
There are 3 ways of heat loss: -
1) Conduction
Heat conduction, or diffusion, happens when two bodies are in direct contact. It also happened within the body itself. It is the direct exchange of kinetic energy between the particles of touching bodies. Heat transfers occur till both the bodies in contact acquire the same temperature.
2)Convection
This happens when the hotter body is kept under the bulk of the cooler fluid. Here the fluid particles move and take heart from the hotter body as they move along.
