Fig. 4.1 shows a large syringe that is sealed at the nozzle by wax. There is a piston inside the syringe. [Figure 4.1] The pressure of the air inside the syringe is equal to atmospheric pressure, 1.0 × 10⁵ Pa. The volume of the air inside the syringe is 1.2 × 10⁻⁴ m³. The area of the end of the piston that is in contact with the air is 3.5 × 10⁻³ m². The friction between the piston and the syringe is negligible.
