What does the constant bombardment of gas molecules against the inside walls of a container produce?

• A. Density
• B. Pressure
• C. Volume
• D. Temperature

Answer: (B)

Verified step by step guidance

1. Understand that gas molecules are in constant, random motion inside a container.
2. Recognize that when these gas molecules collide with the walls of the container, they exert a force on the walls.
3. Recall that pressure is defined as the force exerted per unit area on the walls of the container.
4. Therefore, the constant bombardment of gas molecules against the inside walls produces a measurable force over the surface area, which we call pressure.
5. Note that density, volume, and temperature are different properties: density relates to mass per volume, volume is the space the gas occupies, and temperature relates to the average kinetic energy of the molecules.
