Question

A gas occupies 0.5 m^3 and exerts 2,400 N on the walls of a container. What physical quantity corresponds to the force exerted by the gas on the container's walls?

A) Temperature
B) Pressure
C) Volume
D) Quantity of gas

Answer 1

The physical quantity that corresponds to the 2,400 N force exerted by the gas on the container walls is Pressure (B). Pressure is defined as force per unit area according to the kinetic theory of gases.

Step-by-step explanation:

The physical quantity that corresponds to the force exerted by the gas on the walls of a container is pressure.

According to the kinetic theory of gases, when gas particles move, they collide with the container walls, and these collisions create a force on the walls. This accumulation of force over the container's wall area is defined as pressure, where pressure (P) is the average force per unit area. Therefore, in the scenario given where a gas exerts 2,400 N of force on the walls of a container occupying a volume of 0.5 m³, the relevant physical quantity describing this force is pressure (B) Pressure.
