Q 1857301284.     Consider one mole of perfect gas in a cylinder of unit
cross-section with a piston attached (figure). A spring
(spring constant k)is attached ( unstretched length L) to
the piston and to the bottom of the cylinder. Initially
the spring is unstretched and the gas is in equilibrium.
A certain amount of heat Q is supplied to the gas
causing an increase of value from `V_0` to `V_1`
(a) What is the initial pressure of the system?
(b) What is the final pressure of the system?
(c) Using the first law of thermodynamics, write down a relation between
`Q, p_0 , V, V_0` and `k`.
