Question

Consider a sample of a gas in a cylinder with a movable piston.

Show diagrammatically the changes in the position of the piston, if pressure is increased from 1.0 bar to 2.0 bar at a constant temperature.

Solution

At constant T, P ∝ `1/"V"`

Since, pressure doubles, the volume will become half.
