Question
Ideal gas is taken through process shown in figure:
Options
A.In process AB, work done by system is positive
B.In process AB, heat is rejected out of the system.
C.In process AB, internal energy increases
D.In process AB internal energy decreases and in process BC internal energy increases.
Solution
In process AB T = constant P = increases P α 1/V
or V = decreases ᐃQ = ᐃW . ᐃW = − ve. or ᐃQ = − ve
∴ heat is rejected out of the system.
or V = decreases ᐃQ = ᐃW . ᐃW = − ve. or ᐃQ = − ve
∴ heat is rejected out of the system.
