A spring which is extended by an amount x has a tension Kx. A mass M is placed on the spring; gravity causes the spring to extend. The system starts with the spring extended by an amount Mg/2K. After, a long time the mass and spring reach a new equilibrium position. Given that the spring and its surroundings at a temperature T, obtain an expression for the increase in the entropy of the universe.
