explain, in terms of the kinetic theory of gases?

Question

why the pressure inside a tank decreases as air is released

Answer 1

Boyle's Law:

P1V1 = P2V2

Answer 2

In terms of the Kinetic Theory Of Gases, Pressure results from the collision of air molecules with the walls of the tank. Further, when a molecule collides with the wall its momentum changes, inducing an impulsive force on the wall of the tank.

For a given time interval and density of air, a certain number of air molecules will collide with the walls of the tank, on average.

Release a quantity of air from the tank, and the density decreases, there will now be less collisions per second, on average, than before.

Answer 3

theoritically each molecule has its own kinetic energy that produce a random motion . when tow molecules got impacted or the molecule got impacted with the tank ..... this impacts produce the force of the pressure
P= F.A
this procedure repeats again and again as molecules are in motion.
as well as gas ( or air) released impact rate get decreesed as the resultant motion is directed to the outer area
then no impacts between molecules or between the molecules and the tank then pressure decreases ;)
