Answer:
(a) 
(b) 
(c) 
Explanation:
Hello,
(a) In this case, since entropy remains unchanged, the constant 
should be computed for air as an ideal gas by:
Next, we compute the final temperature:
Thus, the work is computed by:
(b) In this case, since 
is given, we compute the final temperature as well:
And the isentropic work:
(c) Finally, for isothermal, final temperature is not required as it could be computed as:

No of moles = given mass ÷ molecular mass
n = 55.98 ÷ (12+19×2+35.5×2)
I can’t see the picture for some reason but if I were to guess, I would say Pangea.
Answer:
I'd say "a" because not everything with plants and animals is perfectly organized together nothing ever is.
