Why doesn't wind make objects heat up?

Question

Heat is the random motion of atoms and molecules. So why doesn't wind hitting an object cause the object to heat up? I can't see why you wouldn't have energy transferred to the object by the wind.

Answer 1

wind does heat up objects but not very much and it is able also to transport the heat away without any significant temperature difference arising.  At very high "wind" speeds, eg. of a satellite re-entering the earth's atmosphere (or a meteor) there is very intense heating by wind

Answer 2

well the atoms and particles in the air are already coliding with the object, the increase of collisions due to wind is probably only a miniscule increase that no heat change is detected. (This is just a thought, do not know for sure, just a physics majors guess)

Answer 3

This is only a slight amount of energy caused from the air molecules striking a surface, but the molecules themselves not in a high kinetic state, the are just moving fast.

Answer 4

wind cools things down by gaining the heat energy lost by an object.For wind to heat an objest it has to be heated itselfe.

Heat is generated by molecules vibrating against each other

wind is a gas which have weak bonds. so it can't produce heat by itselfe even if it"s atoms are moving

Answer 5

1st, molecules in most objects around us are not free to move, they are a part of a rigid matrix.

2nd, molecules of air hitting molecules of object transfer energy, but the end energy can be in different forms -- vibrational energy (building's wall is shaking when wind hits) or kinetic (waves in the ocean).

So, you're right that the energy is transferred, but the resulting energy is not heat, but some other type.

Answer 6

Because wind at normal speeds isn't strong enough to break the intermolecular forces acting among the atoms of an object and so these atoms can't start moving in a random way.

Answer 7

There are two effects to be concerned about here - friction (heating) and convective heat transfer (heating or cooling).

If the air temperature is lower than the object, the heat input from friction will usually be cancelled by the cooling effect in convection.

If the air temperature is higher than the object, the friction and convection will heat the object.

If they are the same, friction will heat the object.
