draw a set of diagrams to help explain this. (Use red arrows to show the direction of hot air blue arrows to show the direction of cold air.) Match up words to the meanings. Draw a line to join them up.
The heat is being transferred by convection.
An infrared heater uses electromagnetic radiation to heat objects directly, while a convection heater warms the air in a room. Infrared heaters are more efficient for heating a room because they heat objects and people directly, providing instant warmth. Convection heaters take longer to heat a room as they rely on circulating air.
The mode of heat transfer from a room heater is convection. This process involves the transfer of heat through the movement of fluids or gases, such as air. The heater warms the air in the room, causing it to rise and circulate, thus heating the surrounding space.
An infrared heater uses electromagnetic radiation to heat objects directly, while a convection gas heater warms the air in a room through the circulation of heated air.
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.

A space heater is an example of convection because it warms up the air around it. The heater emits heat which causes the air molecules to become less dense and rise, creating a convection current that circulates the warm air throughout the room.
A portable heater primarily uses convection to transfer heat into a room. Air is heated inside the heater, rises, and then circulates throughout the space. Some heaters also emit radiation, where infrared waves directly heat objects in the room, but convection is the main mechanism.
An example of convection heat transfer in everyday life is when hot air rises from a heater and circulates around a room, warming the surrounding air.
it would emit heat in the form of radiation. It will also heat the air which will cause convection. However, these heated gasses will be vented out of the flue so as not to contaminate the air in the room.
A ceramic heater uses a heating element to warm up ceramic plates, which then radiate heat into the room. A convection heater, on the other hand, heats up the air around it and circulates it throughout the room. In terms of efficiency, convection heaters are generally more efficient for heating a room because they heat up the air, which then rises and circulates to evenly distribute heat. Ceramic heaters are more focused and may not heat a room as evenly.
it's because of heat transfer into convection .
A space heater heats a room by transferring heat through convection, radiation, or a combination of both. Convection heaters warm the air, which rises and circulates around the room. Radiant heaters emit infrared radiation that directly heats objects and people in its path.
