The PVT behavior of a certain gas is described by the equation of state: P(V − b) = RT where b is a constant. If in addition CV
is constant, show that: (a) U is a function of T only. (b) γ = const. (c) For a mechanically reversible process, P(V − b)γ = const.

Answer:
The gravitational potential energy equals the work needed to lift the object.
Explanation:
here we know that
work done is given as
Potential energy is given as
force due to gravity is given as
now here if we plug in the value of distance and force in the formula of work done then we will have
so here we got
so we can concluded that
The gravitational potential energy equals the work needed to lift the object.
