Question

explain why volume of a gas decreases on increasing pressure on it at constant temperature?
please answer accordingly and donpt search in hoogle i already checked there and i didnot find a proper answer.​

Answer 1

answer

At constant temperature the kinetic energy per molecule is constant and so is the average magnitude of their momentum. So each molecule will, on average, deliver the same impulse when it hits the inner surface of the container. In order to balance a greater pressure then the molecules must strike more often, which can only happen when there are more of them per unit volume. The total number can’t change, so the volume must decrease.
