What is the unit of coefficient of expansion of solid in Sl system ?

in a reversible adiabatic expansion, entropy of the system

Which one of the following equations does not correctly represent the first law of thermodynamics for the given processes involving an ideal gas? (Assume non-expansion work is zero)

Following graph shows a single stage expansion, then work done by the system is:

Select the correct set of "statement"//s : (P) Work done by the surroundings in case of infinite stage expansion is more than single stage expansion. (Q) Irreversible work is always greater than reversible work. (R ) In an ideal gas in case of single stage expansion and compression, system as well as surroundings are restored back to their orginal states. (S) If gas in thermodynamics is equilibrium is taken from state A to state B, by four successive single stage expansion. Then we can plot four points on the P-V indicator diagram.

Select the correct set of statement/s: I. Work done by the surrounding in case of infinite stage expansion is more than single stage expansion II. Irreversible work is always greater than reversible work. III. On an ideal gas in case of single stage expansion and compression system as well as surrounding are restored back to their original states IV. If gas is in thermodynamic equilibrium is taken from A to state B, by four successive single stage expansions. Then we can plot 4 points on the P-V indicator diagram.
