Question

What gives rise to pressure of a gas​

Answer 1

Answer:

Pressure is caused by the collisions between the atoms of gas and walls of the container as those atoms travel in the confined space. ... More molecules mean more collisions. Like blowing more air into a balloon, the walls of the balloon get tighter. Decrease the volume

Answer 2

At low (ordinary) pressures, real gases behave like ideal gases, so you can use the Ideal Gas Law to determine how to increase the pressure of a system. The Ideal Gas Law states:

▶PV = nRT

Where P is pressure, V is volume, n is the number of moles of a gas, R is Boltzmann's constant, and T is temperature

If we solve for P:

▶P = (nRT)/V
