Unit 3.2 Review

What does the P=F/A equation represent?

• Area equals force divided by pressure

• Force equals pressure times area

• Pressure equals area divided by force

• Pressure equals force times area

How is pressure affected by small areas?

• Pressure becomes zero

• Pressure remains the same

• Pressure decreases

• Pressure increases

Which of the following is a concept of the ideal gas law?
