Answer:
Heat transfer during the process = 0
Work done during the process = - 371.87 KJ
Explanation:
Initial pressure = 0.02 bar
Initial temperature = 200 K
Final pressure = 0.14 bar
Gas constant for helium R = 2.077
This is an isentropic polytropic process so temperature - pressure relationship is given by the following formula,
=
Put all the values in above formula we get,
⇒ =
⇒ = 1.74
⇒ = 348.72 K
This is the final temperature of helium.
For isentropic polytropic process heat transfer to the system is zero.
⇒ ΔQ = 0
Work done W = m × ( -
) ×
⇒ W = 1 × ( 200 - 348.72 ) ×
⇒ W = 371.87 KJ
This is the work done in this process. here negative sign shows that work is done on the gas in the compression of gas.
