QN0038397

An ideal gas goes through a reversible cycle has the - diagram shown below. Process and are adiabatic.

The corresponding diagram for the process is

(A)
(B)
(C)
(D)

Correct Answer: B

Explanation:

In graph ab-process : Isobaric, temperature increases.

bc process : Adiabatic, pressure decreases.

cd process : Isobaric, volume decreases.

da process : Adiabatic, pressure increases.
The above processes correctly represented in diagram (b).

Question (8)

QN0038404

The work done in an adiabatic change in a particular gas depends only upon

(A)
change in volume
(B)
change in temperature
(C)
change in pressure
(D)
None of these

Correct Answer: B

Explanation:

In adiabatic process, no heat is taken or given by the system i.e.,

If is negative (work done on system), then increases & temperature increases and vice-versa. So work done in adiabatic change in particular gas (ideal gas) depends on change in temperature.
