HOW IS THERMAL ENERGY TRANSFERRED?


 

CONDUCTION: when two objects are in contact thermal energy is transferred from one object to the                              other.
CONVECTION: thermal energy travels through a gas or a liquid by convection. Molecules move in                                a circular way.
RADIATION: thermal energy can be transferred through space.
