Izayah Bishop · Answer 1

Answer: The correct answer is Option A.

Explanation:

Heat transfer is defined as the process in which heat is transferred from high temperature to low temperature to maintain equilibrium.

There are 3 modes by which heat can be transferred, they are:

Conduction: This mode of heat transfer occurs whenever a direct contact between two object happens. Convection: This mode of heat transfer occurs whenever a movement of fluid (liquid or gas) takes place. Radiation: This mode of heat transfer occurs whenever a direct transfer of energy through space happens.

Thus, all these three modes involve the heat flow from hot objects to cold objects.

Hence, the correct answer is Option A.
