Describe a convection in a room heated by a radiator?
it hotter
An example of convection?
Hot Air Rising And Cooler Air Falling Is One Example Of Convection Which That Example Is Called Convection Currents. Example Two An old-fashioned radiator creates a convection cell in a room by emitting warm air at the top and drawing in cool air at the bottom.
What is an example for convectioon?
Convection is the movement of molecules in fluids and gasses. An example of convection is a warm radiator. A radiator warms the air near it which causes this air to rise. This also sucks in cold air from near the floor, which also gets heated and rises. This causes a circulation within a room.
What kind of thermal transfer happens when hot air rises?
ConvectionI'll tell you all i know ;) convection is the heat transfer through atoms or molecules that move, so that's liquids or gases. It's difficult to see in gases, it just kind of, happens. If you turn a radiator is turned on and the room is full of cool air, the radiator in the middle will warm up the particles above it and as warm things rise these heated particles will rise, pushing the cool air towards the radiator to be heated too.Image: http://www.revisionworld.com/files/convection%20copy.jpg
A radiator heats a room by heating the air which circulates in convection currents?
Yeah you are right convection currents are movement of the air
Explain how convection could be used to heat a room with a hot radiator on one side of the room?
Hot air rises to the ceiling and as it cools on the far side of the ceiling it sinks back down to the floor on the opposite side of the room from the radiator. It will not evenly heat the room. To get the best comfort level, you need a ceiling fan to push the hot air to the floor. The hot radiator sets up convection currents that transfer thermal energy to the rest of the room and eventually heat the entire room. How do convection currents work? The hot radiator warms the air that is closest to the radiator. The warm air expands, becomes less dense and rises to the top of the room. When the air reaches the top of the room it is pushed sideways towards the far wall by the more recently warmed air rising from the radiator below. In this way warm air moves to the other side of the room. Once on the other side of the room the air drops down both because it has cooled a little and because the air behind it continues to push on it. The air then continues to circulate back to the radiator and repeat the process.
How does a room with a hot radiator get hot?
The room heats by convection transfer into the air, aided by humidity produced when water is heated.

What heat transfer processes change air temperature?
Convection is the heat transfer through atoms or molecules that move, so that's liquids or gases. If you turn a radiator is turned on and the room is full of cool air, the radiator in the middle will warm up the particles above it and as warm things rise these heated particles will rise, pushing the cool air towards the radiator to be heated too.

How does a hot water radiator heat a room?
The hot water heats the metal of the radiator, which heats the surrounding air. The warm air circles round the room.
What are the main uses for thermal energy?
Thermal energy is used to keep us warm. An example of a use of thermal energy is a radiator. This is because a radiator is used to warm a room and keep people warm.
