Question

The molecules which evaporate into the gas phase are the ones traveling with ________ velocity.

Answer 1

The appropriate response is high. The best approach to consider it is those molecules have more vitality than the normal and it is unequivocally those higher enthusiastic ones that have enough vitality to break the intra-molecular forces and leave. By the way this is the reason when we sweat we chill off - the most enthusiastic molecules vanish diverting warmth.

Answer 2

Explanation:

In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they tend to move rapidly from one place to another leading to more number of collisions.  

Therefore, when number of collisions increases then force applied by the molecules on each other also increases.

As a result, velocity of the particles increases.

Therefore, we can conclude that the molecules which evaporate into the gas phase are the ones traveling with high velocity.
