Question 9
F

A sealed syringe contains 60 cm3 of air at a pressure of 100 kPa.

The plunger is pushed in until the volume of the air is 20 cm3. The temperature of the air stays the same.

Use the equation: pressure×volume=constant\text{pressure} \times \text{volume} = \text{constant}pressure×volume=constant

What is the new pressure of the air?
