Warm air flows toward the ceiling and cool toward the floor.
(expansion with heat results in lower density)
because convection causes the warm air to rise. This creates a cycle where the warm air moves to the top of the room.
Correct! A radiator heats the air in a room through convection. As the air near the radiator heats up, it becomes less dense and rises, creating a convection current that circulates the warmer air throughout the room.
The answer is convection. Convection is the transfer of heat through the movement of fluids (liquids or gases), such as air becoming warm and rising as it is heated by the furnace, creating a convection current that warms the room.

Most heaters heat a room primarily through convection. The heater warms the air, which then circulates around the room. However, some heaters also emit infrared radiation that directly heats objects and people in the room.
No. The crust is rigid; it does not allow convection.
