Convection is the process by which heat is transferred by a "fluid" (which, in this case, can actually mean a liquid or a moving gas - both are considered "fluids").
Heat is always transferred from an area of high heat to an area of low heat, regardless of the method. When your hand touches a hot stove, heat moves from the stove to your hand to try to "even out" the amount of heat between the two objects.
In convection, heat is first transferred from an area of high heat to the fluid, then from the fluid to an area of (relatively) lower heat.
Imagine you're sitting downwind of a bonfire. The wood has lots of heat - some of it is transferred to the air. The air is pushed toward you by wind, and when the air hits your skin, there is another heat transfer because your skin has less heat than the air. The net result is a transfer of heat from the wood to your skin, and we say this is by convection.
Another example might be the way everything in a small kitchen gets warm in a hurry when things are baking in a hot oven. Some radiation occurs, but lots of air picks up heat from the stove, and then rises to be displaced by cooler air. The hot air heats things in the upper regions of the kitchen, and then cools and sinks. It then may return to the stove to pick up more heat as hot air there continues to circulate upward. Convection currents in air transfer heat.
What else can I help you with?
How heat transfer?
Heat can be transfered by convection, radiation or conduction.
How is heat transfered in liquids and gasses?
Mostly by convection
What are some ways heat is transfered?
By conduction,convection and radiation
Heat can be transfered by conduction or radiation?
Er, yes it can - and by convection.
What is the main way heat is transfered in the troposphere?
Convection Currents
What are the 3 methods by which heat can be transfered?
Conduction, convection, radiation.
What are the three methods heat is transfered?
The three methods heat is transferred by are:Conduction, convection and radiation.
Only when is transfered is it called heat?
Yep. Only when the fast moving particles are transferring in Conduction,Convection and Radiation is it called "Heat".
How is heat energy transferd?
Heat is transfered through conduction, direct contact, convection, movement through liquids and gases, and radiation.
Transfer of energy by movement of particles is?
Convection is the movement of particles due to a gradient of energy. Heat energy is thus transfered by the moving particles.
How is heat naturally transfered between objects?
The mechanisms to transfer heat are conduction, convection, and radiation. Heat will naturally flow from hotter to colder objects.
How does the transfer of heat differs between conduction and convection?
In conduction, heat is transferred through direct contact between materials, such as a metal spoon heating up when placed in a hot liquid. In convection, heat is transferred through the movement of fluids, like when hot air rises and cold air sinks, creating a cycle of heat transfer.
