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.
What else can I help you with?
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 will happens to convection currents when liquid or gas is no longer heated?
When a liquid or gas is no longer heated, the heat source that drives convection currents is removed. As a result, the temperature differential that causes the fluid to circulate diminishes, and eventually the convection currents will slow down and stop as the fluid reaches thermal equilibrium.
What two states of matter can occur in convection?
Convection currents are in the liquid and gas states.
Heat convection what is?
Convection is the transfer of heat by circulation through a gas or liquid.
What are convection currents created by?
Convection currents are the flow of fluid (liquid or gas) caused by the molecular motion resulting from the transfer of heat through the fluid. In meteorology it is the vertical movement of atmospheric gases caused by heat, atmospheric pressure, condensation of water vapor, and other factors.
Which method of heat transfer causes actual movement of material?
Both conduction and convection. Conduction involves the small movements of individual particles, convection can be on a much larger scale with a hot liquid or gas rising and a cool liquid or gas dropping.
What type of currents form as hot and cool portion of a liquid or gas move?
Convection currents.
Movement of heat by liquid or gas?
convection
What is the transfer of heat by a liquid or gas?
convection
