What relationship can be interpreted from the diagram?

• As volume decreases, pressure decreases

• As pressure increases, volume increases

• As moles increase, temperature increases

What will happen to the volume of a gas under constant temperature if the pressure increases?

• Increase

• Decrease

• Nothing

• Explosion!
