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

Question

Philoid · Accepted Answer

One should expect more evaporation.

Explanation

1. Evaporation is the transition from liquid state to gaseous state. To do so heat is provided so that forces holding molecule together in liquid state are weakened and vapor state can be achieved.

2. If molecules are not allowed collide among themselves this means that interaction between them is very weak. Hence, more evaporation will take place.
