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.

An example of a situation in which an egg is receiving thermal energy through convection -

• The egg is kept warm by its mother in the nest.
• An egg cracked on a hot sidewalk starts to cook.
• The egg is hard boiled in a pot of water.
• A metal pan on the stove fries the egg.

Thermal energy transfer by conduction is accomplished when heat moves from a warmer object to a cooler one by -

• moving across a solid barrier.
• being carried in a fluid, like air or water.
• coming in direct physical contact with it.
• traveling through empty space.
