ANSWERS:

Explanation:
Given:
Piston cylinder assembly which mean that the process is constant pressure process P=C.
<u>AMMONIA </u>
state(1)
saturated vapor 
The temperature 
Isothermal process 
a)
( double)
b)
(reduced by half)
To find the final state by giving the quality in lbf/in we assume the friction is neglected and the system is in equilibrium.
state(1)
using PVT data for saturated ammonia

then the state exists in the supper heated region.
a) from standard data



assume linear interpolation


b)

from standard data

then the state exist in the wet zone


Answer: False
