Thermal Energy

Conduction can only occur between two objects when –

• one object is less dense than the other.
• both objects are in physical contact with each other.
• one of the objects is made of a metal.
• both objects are exactly the same temperature.

In the situation illustrated, how will heat energy move? Heat energy will be transferred from –

• the hot plate to the water by conduction

• the water to the hot plate by conduction.
