The temperature and volume in a closed container of gas remain constant. If the number of particles of gas is increased, what will happen to the gas pressure?

-it will increase

-it will decrease

-it will remain constant

-you cannot predict it

A - It will increase

Explanation:

Take for instance,

The number of particles (10000) present initially is less in a per unit volume say in 1 mL.

The number of particles increases (20000) in the same volume 1mL.

So, the pressure will increase in the container since 10000 particles is present in a low volume of 0.5 mL now.

We know as volume decreases the pressure will increase as per Boyle's law.
