Explanation:
(a) The given data is as follows.
mass = 1 kg = 1000 g (as 1 kg = 1000 g)
Molar mass of = 17 g/mol
= 2.5 bar =
(as 1 bar =
)
= 5 bar =
= 30 + 273 = 303 K
For adiabatic process, = constant = k
= 1.33 =
(as PV = nRT)
=
= 0.352
Also, w =
=
= -84318.2 J
As 1 kJ = 1000 J. So, -84318.2 J = -84.318 kJ
Hence, the work required in kJ is -84318.2 J.
(b) It is known that for adiabatic system Q = 0,
= -w
dT =
=
= 895.93 K
We known that dT =
so, 895.93 = 303 K -
= (895.93 - 303)K
= 592.93 K
= (592.93 - 273.15)^{o}C
=
Hence, the final temperature is .
