Objects cool at a rate depending on the temperature difference between the hot object and its surroundings. Probably the hand is warmer than the air, so usually the object will cool faster in the air.
Blowing air over a hot plate is generally more effective in cooling it down, as it promotes faster heat dissipation. This is because blowing helps to increase air circulation and disperse the heat, whereas sucking air might not cool the plate down as efficiently.
The steam you see coming off a hot bowl of soup are the hotter, faster moving particles evaporating into the air, leaving slower-moving, cool particles behind. But these evaporated particles form a little cloud of vapor above the soup, which prevents the other hot particles from evaporating. When you blow on your soup, you blow away the vapor. This allows more of the faster moving particles to evaporate.
Rural areas cool off faster than cities because they have less concrete and buildings that retain heat. In cities, concrete and buildings absorb heat during the day and release it slowly at night, resulting in higher nighttime temperatures. Additionally, rural areas have less air pollution that can trap heat near the surface.
A person will run faster in air as without oxygen they would die. A dead person doesn't move very quickly. That said if there was no requirement for oxygen, there would be no air resistance in a vacuum and logically they would move at a negligibly grater speed.
it doesn't, heat causes perspiration as when the sweat is evaporated off of the skin by cool air the air brushes on the skin and cools you down.
jaguars blow, the ac is making the cool air. turn it off, to stop cool the cool air.

Shuts off intake from outside-cools faster, but no fresh air.
There's not enough cool air for convection to take place.
in the lower atmosphere the air gets colder with increasing altitude.
To cool people off and help them survive!
No. While the air conditioner is on, keep the windows closed to keep the cool air from escaping to the outside.
A desert will cool off much more quickly as there is little humidity or cloud cover that would hold in the heat of the day.
it pulls all hot air out from the house
please i need a help my ac keep blowing bhot and cool i have check and refill it but i still get the hot and cool air in stead off cool air

Buy an air conditioner. Another way is to put fans in the room and get the air circulating
