Question

If the molecules were not allowed to collide among themselves, would you expect more evaporation or less evaporation?

Answer 1

If the molecules were not allowed to collide among themselves, we can expect more evaporation.

Explanation:

• The molecules will have a long mean free path when they are not allowed to collide with each other, thus making a faster evaporation. There will be a low external pressure in vacuum.

• Thus, at very low temperature, the liquid will boil and evaporate. We can expect more evaporation too.

• It is to be basically understood that the evaporation is a process in which the liquid is converted in gas.

• For performing this, the heat is given to the liquid, so that the molecules that are forced to hold the molecules are weakened and there will be an achievement of the vapor state.
