Like a pan of water on a stove, the warmed water expands, becoming less dense, and lighter, so it rises to the top, and cold water circulates down to the bottom, where it is warmed and rises again. This method of heat transfer is called convection and it works with boiling water, heating the air in a room, or warming the atmosphere.

A method of heat transfer when energy is transferred by currents in a liquid or gas?
convection
Is the correct definition of convection?
the transfer of heat by currents within a liquid or gas
A sentences with convection?
Convection- heat transfer in a gas or liquid by the circulation of currents from one region to another.
Is warming ocean water through water currents radiation?
No. Heat transfer through a liquid or gas by currents is convection.
What is a convection current caused by?
The liquid or gas which transfers the heat can circulate round and round between the hot and cold regions. The flow of liquid or gas is called a convection current. Convection currents are caused by changes in density.
What two states of matter can occur in convection?
Convection currents are in the liquid and gas states.
What is Convection is the circulation of what gas or liquid?
The transfer of heat within a gas or liquid medium by the circulation of currents from one location to another. Note that gravity when present plays a part.
What is heat convection?
Convection is the transfer of heat by circulation through a gas or liquid.
Heat convection what is?
Convection is the transfer of heat by circulation through a gas or liquid.
What type of currents form as hot and cool portion of a liquid or gas move?
Convection currents.
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.
What is the transfer of heat by a liquid or gas?
convection
