Thermal Energy

Front

Conduction can only occur between two objects when –

Back

both objects are in physical contact with each other.

Front

In the situation illustrated, how will heat energy move?

Back

the hot plate to the water by conduction.

Front

Radiation is a method of thermal energy transfer that moves -

Back

through empty space.

Front

Example of an egg receiving thermal energy through convection.

Back

The egg is hard boiled in a pot of water.
