3  The atmospheric pressure and hydrostatic pressure

4. In container B the collision of the particles is high because  the weight of acting on the piston is high and this increases the pressures due to the reduction in the area followed by C and then A

5.Diffusion is the net movement of a substance (e.g., an atom, ion or molecule) from a region of high  concentration to a region of low concentration.diffusion is a result of the energy of the system (temperature). The movement of the molecules (or atoms) allow them to disperse themselves amongst like sized particles

6.At room temperature, they are going about 300 meters per second. That’s equal to about 670 miles per hour. gas as a large number of molecules which move independently of one another, except for occasional collisions with each other or with the walls of their container. When they do collide, the collision occurs with no net loss of energy
