How is convection applied to heating rooms?

Answer 1

Convection is a method of transfering heat energy throughout fluids (liquids and gases). Since the molecules that make up fluids are spaced further apart than those that make up soilds, the vibrational energy used

Answer 2

Hot air rises, so as the air from the heater goes upwards cooler air sinks and becomes available for the heater to warm. That newly-warmed air rises above the, by now, slightly cooled warm air emitted just beforehand.

Slowly all the cold air has sunk to the level where it can be heated and the warmest air is always going to the top of the room and pushing any air colder than it downwards. After a while the heater is heating the air faster than it is cooling, and the room reaches a stable temperature.

Answer 3

When we turn our heater on, the first part of the room warms up. The particles of the air move more rapidly, they push out and up. Hot air rises and meets the ceiling of the room. The air then cools and drops down along the walls. A convection current forms in the room until the entire rooms becomes warm, just like the pot of soup did.

Answer 4

That depends on the type of heating system. Central heating systems that blow air into living areas through vents after heating it are heating primarily by convection. The older hot water systems that use radiators with hot water flowing through them are heating primarily by conduction, although convection is also occurring because the heating of the air around the radiators causes it to rise. Space heaters with red-hot heating elements are heating primarily by radiation. Again, convection is also at work, especially if the space heater has a fan.

Answer 5

It circulates through the house, like for example, take a radiator, and it moves the air throughout the rook or practically the whole house.

Answer 6

Convection occurs because warm air is lighter than cold air, so a source of heat at floor level will cause warm air currents to circulate through the room.

Answer 7

Heat leaves through the ceiling due to it being colder outside than inside. There you go :) Hope this helped.
