The flat base of a pressurized gas cylinder is in contact with the floor. The area of the base in contact with the floor is 0.025 m20.025\text{ m}^20.025 m2. The cylinder exerts a pressure on the floor of 180 kN/m2180\text{ kN/m}^2180 kN/m2.
Calculate the force exerted on the floor by the cylinder.
The cylinder is filled with gas at high pressure.
Use ideas about molecules to explain how this gas exerts a pressure on the inside walls of the cylinder.
