How does density affect the transfer in heat?
This is heat loss from the process of expansion. The heat energy in a gas when that gas is expanded through a nozzle (or orifice) is used to expand that gas from a high pressure (compressed) region to a low pressure region causing the gas to cool. The heat is used to produce the expansion.
Convection is the transfer of heat through what?
Convection is "the transfer of heat through the motion of molecules in a fluid."
What does Heat transfer by convection requires to transfer heat?
A liquid - - - which changes density when heated, and A gravity field.
What is the transfer of energy as heat caused by the collision of molecules?
When molecules collide and there is a transfer of energy as heat, this is called conduction. When fluids of different temperatures transfer energy by movement, this is called convection.
The transfer of heat by the movement of molecules which carry the heat is called?
CONVECTION
What is the transfer of heat by the movement of molecules which carry the heat?
Conduction.

Why do water molecules retain heat energy?
Water molecules retain energy due to heat transfer.
When molecules collide together to transfer heat is called?
Conduction of heat.

CONVECTION
How does heat from a radiator transfer?
The heat energy from the radiator transfers that energy to the air molecules next to it. Those molecules then transfer that heat energy to the molecules next to them. This process continues until all the molecules are at the same energy level. This process is call conduction.
What happens when fast moving molecules touch other molecules?
Heat transfer
What is the energy transfer process that does not require the presence of molecules to transfer heat?
Radiation
