is the transfer of heat in air or a fluid through current .An example is pot of water warming up on a hot stove ..As this occurs the cold water sinks.So hot air rises ,coolsand falls
why water rises when heated
A was heated.an increase in temperature caused the water molecules to gain energy and move more rapidly,which resulted in water molecules that are farther apart and an increase in water volume.When water is heated,it expands ,or increases in volume
