Question

How is pressure related to kinetic energy?

Answer 1

For an ideal gas, the relation is given by

Where K =N*KEbar (N=total number of molecules, KEbar= average kinetic energy)

Explanation:

Given the following ideal gas relation

Where the energy of the molecules is given by

setting
, where N is total molecules

Through rearrangement, you get
.
