How is the room heated using a room heater? Explain
Answers
Answer:
Explanation:
That rather depends upon the style of heater.
Electric fanless heaters are sometimes called convectors, which is mostly a clue. The air heated within it is distributed by convection. Fan heaters use an electric fan to boost, or assist, the natural convection. In practice this is essentially the same device, scaled down into a smaller box. But although at room scale convection dominates, within the case of the heater the air is heated by coming into contact with the element, by conduction.
A water-filled central heating radiator, (despite the name) works in a similar manner. We ignore the tiny amount of radiant heat, air is warmed by conduction and circulated by convection.
But what of wall-hung bathroom heaters, or those glowing 2-bar electric fires? In those the dominant effect is radiant, albeit with some convection at a distance.
Coal fires , also are mostly radiant in action, wood-burning enclosed stoves are mostly conduction/convection like the first examples, but if too hot to touch when in use there will be a significant radiant component too.
The world is not a simple place. Except in homework questions.
Answer:
the room is heated using a room heater like the fire heat. the room heater has a power or ability to give heat and a temperature that a person needs.
