Question

What happens to the pressure of a gas when the amount of gas increases? Thanks!

Answer 1

The pressure increases

Explanation:

The pressure is the result of collisions between the molecules of a gas. An increase in the number of molecules will increase the number of collisions which will in turn increase the pressure.

Answer 2

Well `"pressure"` is formally `"force per unit area"`...

Explanation:

And given a FIXED volume...the addition of MORE gaseous particles should reasonably increase the pressure proportionally.

And recall the ideal gas law...

`PV=nRT`...given FIXED temperature, and fixed volume, the addition of more gaseous particles will result in increased pressure.
