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.
What else can I help you with?
Explain how you could feel heat from a radiator by more than one method of transfer?
You can feel heat from a radiator through conduction, where direct contact with the hot radiator causes heat to transfer from the radiator to your body. You can also feel heat through convection, where the hot air near the radiator rises, creating a current that carries heat to you.
How does heat get from inside the boiler to the wall behind the radiator?
Conduction of heat energy from the source to the water in the boiler. A pump moves the hot water to the radiator.The heat radiates out from the radiator to the air, where convection then circulates it through the room.
How is thermal energy produced by the furnace transferred to the radiator?
Thermal energy from the furnace is transferred to the radiator through convection. Heated air or water circulates through pipes from the furnace to the radiator, where it releases heat into the room through a process called convection. This heat transfer warms the surrounding air in the room.
How could convection be used to heat a room with a hot radiator?
A hot radiator heats air in contact with it, causing the air to rise and circulate around the room through convection. As the heated air moves around the room, it transfers heat to the surrounding surfaces and objects, raising the overall temperature of the room. This process helps to distribute heat evenly throughout the space, creating a warmer environment.
Which process conduction convection or radiation is used to remove heat from car raditor?
Convection is the primary process used to remove heat from a car radiator. As the hot coolant flows through the radiator, it transfers heat to the surrounding air through convection. The air passing over the radiator fins helps to dissipate heat quickly, keeping the engine at a safe operating temperature.

How is heat transferred through a radiator?
Heat is transferred through a radiator primarily by convection. As hot water or steam flows through the radiator, it warms the metal fins of the radiator. The warm metal then heats the surrounding air, which rises and creates a convection current, transferring heat into the room.
By what method does a radiator heat the air near it?
convection
How does the heat energy get from the hot water to the outside of the radiator?
The hot water is in contact with the metal casing of the radiator, so that metal radiator takes some heat from the water. The heat then passes from the inside metal of radiator to the outside metal of the radiator through convection. The outside metal of the radiator then passes it to the air that is blowing by it outside.

How does heat from a radiator transfer?
The heat energy from the radiator transfers that energy to the air molecules next to it. Those molecules then transfer that heat energy to the molecules next to them. This process continues until all the molecules are at the same energy level. This process is call conduction.
Which example of heat transfer is due mainly to convention?
Heating a room with a radiator is an example of heat transfer mainly through convection. As the air surrounding the radiator is heated, it becomes less dense and rises, creating a convection current that circulates warm air around the room.
How does convection occur in radiators?
Convection is defined in the related link. It requires molecular movement to carry the heat away. The exposed surface of a radiator is hot and in contact with air. The air molecules, when in contact with the surface, pick up heat energy and move away, carrying the heat with them -- hence, convection. =============================
Explain how friction is involved in energy transformation?
Friction creates heat - heat travels by convection, conduction or radiation.
