QUESTION 8 A cylinder has a massless piston of surface area A = 7.87x103 m at one end and is closed at the other. It contains V = 0.69 litres of air at a temperature of T = 273 K and a pressure of p = 1.41x10 5 Nm 2. If a force of F = 1.81x10 3 N were suddenly applied to the piston, the resultant displacement of the piston is s = 0.94 mm. Assume that no heat is exchanged i.e. Q = 0. Calculate the change in entropy of the gas (once it has reached equilibrium) using the thermodynamic identity. 2
