pressure is exerted by the gas molecules is the result of
the collisions of the gas molecules against the walls of the
container (or) gas molecules in the container are
undergo collisions with the walls of the container and produces the
pressure
so the force of gas particles against the walls of the container is called => PRESSURE

Please answer & explain 22-25
22. Pressure is created when a gas is compressed and the temperature is decreased proportionally b) gas particles collide with the sides of their container more gas particles are added and the volume is increased proportionally gas particles are removed and the volume stays the same 23. because In response to Boyle's law, the pressure of a gas increases as the volume a) decreases; the gas particles strike the walls of the container more often...
