Convection occurs when a warm liquid or gas moves moves into a region where the surrounding liquid or gas is a different temperature. An example of this is a warm gas rising into a region where the surrounding gas is cooler due to the lower density of the warm gas. Movement of gases and liquid due to differences in density (because of differences in temperature) is referred to as "natural convection". When the movement is caused by another force such as a pump or a fan or a mixing blade, then it is termed "forced convection".

What is the thermal energy transfer that occurs by the motion of fluid in liquid or gas?
you guys dont know this omg bye
The transmission of heat requiring the movement of a liquid or a gas?
The transmission of heat requiring the movement of a liquid or a gas is called convection.
Describe how heat is transferred from one place to another by convection?
Convection is the transfer of heat in a gas or liquid caused by differences in density, thus when molecules in the medium are heated they form a less dense gas or liquid which then rises through the cooler unheated medium, thus creating moving warm currents.
What medium does convection travel through?
Gas or liquid
Does convection involve a moving liquid or gas?
I believe it involves a moving gas...
Do convection currents happen when cool air rises?
No. Convection occurs when warm air rises and cool air sinks. It is not limited to air, either, but can occur in virtually any liquid or gas.
Where does convection mostly occur?
Convection occurs in any liquid or gas that has variations in density due to uneven heating.

When does condensation happen?
condensation occurs when a gas turns into a liquid
What are convection waves?
Convection waves are a churning upward motion from the up welling of warm liquid or gas, and the concurrent downward flow of cooler material to take its place.
Where does convection occur?
Convection occurs when and where a fluid is in a gravity field and heat is applied to its base.
What role do convection currents play as you heat a pot of water?
The role convection currents play as you heat a pot of water is transferring heat by movements of a liqiud or a gas because when when convection occurs it occurs in a circular pattern.
What is the transfer of heat by a liquid or gas?
convection
Movement of heat by liquid or gas?
convection
What does convection travel through?
Gas or liquid
What is a directed flow of gas or liquid?
convection
What is heat convection?
Convection is the transfer of heat by circulation through a gas or liquid.
