A heavy steel container stands on a flat horizontal floor.
Describe the arrangement, separation, and motion of the particles in the solid steel.
The container is filled with gas. Describe how the particles of the gas exert a pressure on the inner walls of the container.
The weight of the container is 540 N540\text{ N}540 N. The contact area of the container's base on the floor is 360 cm2360\text{ cm}^2360 cm2.
Calculate the pressure exerted on the floor by the container.
