If you have a bottle with Helium & Nitrogen at room temperature, how do the speed of the particles compare?

The Helium particles will be faster than the Nitrogen particles

Explanation:

This is because the particles of both elements have the same average kinetic energy (they are at the same temperature), but Nitrogen atoms are heavier than Helium atoms, and therefore they move slower in accordance to Newton's second law of motion, f=ma. The larger massed Nitrogen atoms take more energy to move so they are slower because both particles have the same energy.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
