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.

Does blowing work better than sucking when you are trying cool down a hotplate?

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.


Why does blowing on soup make it cool off faster?

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.


Why rural areas (away from cities) cool off faster than cities?

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.


Will a person be able to run faster in air or in vacuum?

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.


How does perspiration causes heat?

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.
