Less massive molecules tend to escape from an atmosphere more often than more massive ones because
A. they are more buoyant.
B. the gravitational force on them is less.
C. they are smaller and thus experience fewer collisions on their way out.
D. they are moving faster.

Respuesta :

We can confirm that less massive molecules tend to escape from an atmosphere more often than more massive ones because they are moving faster.

How does speed help molecules escape?

This has to do with the energy of the molecules. Speed comes with its higher kinetic energy. This higher level of energy helps the molecules to escape by giving them enough energy to overpower the force of gravity acting upon them in the atmosphere.

Therefore, we can confirm that less massive molecules tend to escape from an atmosphere more often than more massive ones because they are moving faster.
