Expert Solution
Step 1
As both questions are not related and it is not mentioned which to be solved, hence Solving first question.
A)
Given
m = 2.5 g = 0.0025 kg
v = 0.01 m3
T = 30°C = 303 K
For ideal gas,
R = 0.287KJ/kg , gamma = 1.4
Process a-b = adiabatic expansion
Process b-c = isothermal expansion
Process c-d = polytropic compression(n = 1.25)
