Answer:

(a) Conduction of heat occurs when molecules increase in temperature; they vibrate, and this vibration and movement passes the heat energy to the surrounding molecules.

(b) Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids

(c) Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object
