A cylinder of length

L

has a thin massless piston fixed in such a way that it divides the cylinder into two equal parts. The cylinder is kept in a large heat bath at temperature

T .

The left side of the piston contains

2

moles of an ideal gas at pressure

4 P_{0}

and the right side contains the same gas at pressure

P_{0} .

Now the piston is released. The heat absorbed by the gas in the process of equilibration is

2 R T \ln (\frac{k_{1}}{5}) + \frac{1}{2} R T \ln (\frac{k_{2}}{5}), k_{1}, k_{2}

being integers. The value of

k_{1} + k_{2}
