A cylinder is closed by a massless piston of cross sectional area A which is connected to a spring of constant k. With the spring relaxed, the cylinder is filled with a gas. The initial pressure, volume and temperature are P_{i}V_{i}and T_{i}. How high will the piston rise if its temperature is increased to a final value of T_{f}?

2. Relevant equations

3. The attempt at a solution

I tried to find P_{f}and V_{f}.

P_{f}= P_{i}+ kx/A

V_{f}= V_{i}+ Ax

I then wrote the universal gas law for P_{f}T_{f}and V_{f}but I doubt this is correct because the equation was crazy long and complicated.
