Question

the force of air particles over an area is
temperature.
pressure.
volume
kelvins.

Explanation:

To solve this, we analyze each option:

• Temperature is a measure of heat, not force over area.
• Pressure is defined as force per unit area, so air particles' force over an area is pressure.
• Volume is the space occupied, not related to force over area.
• Kelvins is a temperature unit, not a force - related quantity.

Answer:

B. pressure
