Question

Thermodynamic processes are indicated in the following diagram.

Match the following

	Column-I	Column-II
P.	Process I	A. Adiabatic
Q.	Process II	B. lsobaric
R.	Process III	C. Isochoric
S.	Process IV	D. Isothermal

(a) P → C, Q → A, R → D, S  → B

(b) P → C, Q  → D, R → B, S  → A

(c) P → D, Q  → B, R → A, S → C

(d) P→ A, Q → C, R → D, S → B 

Answer 1

Correct option (a) P → C, Q → A, R → D, S  → B

Explanation

 In process I, volume is constant 

.'. Process I → Isochoric; P → C

As slope of curve II is more than the slope of curve III.

Process II → Adiabatic and Process III → Isothermal

.'. Q → A, R → D

In process IV, pressure is constant 

Process IV → Isobaric; S → B
