Your heater is not blowing air you can feel heat but will not blow?

The heater in all cars use a fan motor to blow the hot air. If you do not feel blowing air the fan is broken and needs to be replaced OR the fuse to the fan motor is burned out and needs to be replaced OR the fan switch that turns on the fan motor is bad OR the wires running to all of these is not connected somewhere. The solution? Check for a fuse in the fusebox that says "Blower" or "Fan". Remove it and put a new one in. If this does not work bring it to someone to test the other things, you cannot do it yourself.

Explain the following statement you feel cooler on a hot day when you turn on a fan even though the air being blown around is hot?

Before you turn on a fan, the air is essentially hot because it is still and there is no circulation byconvection of the air currents. When you turn on the fan, it sparks a circulation where the hot air at the top flows to the opposite side of the room, and then eventually becomes cooler and more dense, falls to the floor, and is pushed back towards the fan by the incoming hot air. So, when you turn on the air, the fan is just cirulating hot air, not making it colder. The air only becomes cooler when it flows away from the fan.

Does a portable cooling fan cool the air?

If it is just a fan, it will not cool it, it will simply blow the air around. To cool the air, you need a portable air conditioner. This will suck air in, cool it down, vent the hot air out (usually through the window, but can also be vented out through the roof or into a different room) and put the remaining cool air back into your room.

Why is it that when you blow air out your wide open mouth it is hot air but when you blow out of a narrow mouth it is cold?

this is because the faster air moves the colder it feels. like a fan on a hot day,the faster it spins the better it feels but the temperature dosent change. the 'windchill' factor is the same idea too the temperature dosent change but the harder the wind blows the colder it feels..
