Because it's been in the body, and has taken up the temperature of the body.
When a balloon is blown up by mouth, it will not float, but fall to the ground. This is because the air inside is the same density as the air outside. For a balloon to float up into the air, it must be inflated with a gas that is lighter than air - such as helium.
From Wikipedia.org: In 1978 Presto introduced the Popcorn Pumper, a popper for consumer use in the home, which used hot air blown up through the kernals. By cooking without oil, it reduced the calories and fat in the finished product. It was also faster and easier than pan-fry popping.
A vent allows for ventilation of air (allowing air in or out).
Air enters the the respiratory tract through either the nose or mouth.
It is because a hot air is a light matter while a cold air is a heavy matter of gas. Like, the difference of low(hot) pressure and high(cold) pressure area.
air that is blown across the mouth hole.
The Buccinator
Evaporation
A hot air balloon can stay in the air because the hot air is less dense than cool air. The hot air that is blown into the balloon causes it to rise and a burner is used to heat the air inside of the balloon to keep it floating.
Possible blown fuse
so that limestone can decompose to form CO2 and CaO
A blown fuse, lack of refrigerant or a blown gasket on your compressor to name a few.
Well a flute can be compared to a recorder because they are both played by blowing air out of your mouth to produce sound. The difference is just that a flute is blown ACROSS and a recorder is blown INTO.
See if the compressor is cycling on and off. If not, the fuse is blown. if it is and you still have only hot air, then it probably has a leak and needs repair and recharging.

blowing cool air, is the air only in your mouth... warm air comes from your lungs. temperature also varies by how open your mouth is while blowing air out
because no matter waht temp. the air is, air wipes of the body heat from your skin so you will be cool
Compressor not running, blown fuse, low of freon.
