<h3>What is heat energy?</h3>
Heat energy is a form of energy that exists due to a temperature difference between two objects.
Heat energy flows from an object at higher temperature to an object at a lower temperature.
Heat transfer by conduction involves the vibration of particles of the medium transferring heat due to contact between the two objects.
Therefore, heat flow by conduction requires that the two systems must not be touching each another.
