Question

Pressure produces a net force on the wall of a gas container. This force occurs at a __________ angle. What one word completes the sentence?

a. Right
b. Perpendicular
c. Random
d. Tangential

Answer 1

The force exerted on the wall of a gas container due to pressure is always perpendicular to the surface of the container.

Step-by-step explanation:

The force exerted on the wall of a gas container due to pressure is always perpendicular to the surface of the container. This is because fluid pressure has no direction, being a scalar quantity, but the forces due to pressure are always exerted perpendicular to any surface.

For example, in a static fluid enclosed in a tank, the force exerted on the walls of the tank is exerted perpendicular to the inside surface, as shown in the tire in the diagram.

In summary, the word that completes the sentence is perpendicular.
