Answer:

Explanation:
Given that
T₁ = 290 K
P₁ = 100 KPa
Power P =5.5 KW
mass flow rate

Lets take the exit temperature = T₂
We know that


If we assume that process inside the compressor is adiabatic then we can say that





That is why the exit pressure will be 4091 KPa.
Answer:
A.
Explanation:
more heat = heat energy becomes more kinetic energy = more particle collision
I believe that the answer is a.
