A student investigates how the volume of a gas varies with its temperature. Air is trapped in a transparent cylinder of diameter d with a movable piston as shown in Fig. 2.1. h d cylinder trapped air movable piston Fig. 2.1 The distance between the base of the cylinder and the bottom of the piston is h. The trapped air is heated by placing the cylinder in water of temperature θ. The increase in temperature of the trapped air causes the piston to move. When the piston stops moving, the value of h is measured. For each value of h, the volume V of the trapped air is calculated. The experiment is repeated for different values of θ. It is suggested that V and θ are related by the equation pV = Yk (θ + Z ) where k is the Boltzmann constant, p is the atmospheric pressure, and Y and Z are constants.
