Question

One liter of hot air will be heavier than one liter of cold air.

a. True
b. False

​

Answer 1

Cold air is denser than warm air. The molecules are packed closer together. ... The more water vapor that is in the air, the less dense the air becomes. That is why cold, dry air is much heavier than warm, humid air. Therefore answer is FALSE

Answer 2

Answer : Wrong

It is incorrect that one liters of hot air will be heavier than one liter cold air.

Other information :

One liter cold air will be heavy by one liter hot air.

Increase pressure and push in a quantity to increase more molecules.

It gets cool in the atmosphere but the density is low because the pressure to push the molecules together is less.
