Question

The thermodynamical processes are indicated in the following diagram:

Match the following

Column I	Column II
P. Process I	a. Adiabatic
Q. Process II	b. Isobaric
R. Process III	c. Isochoric
S. Process IV	d. Isothermal

(1) P → c, Q → a, R → d, S → b

(2) P → c, Q → d, R → b, S → a

(3) P → d, Q → b, R → a, S → c

(4) P → a, Q → c, R → d, S → b

Answer 1

Correct option is :(1) P \(\rightarrow\) c, Q \(\rightarrow\) a, R \(\rightarrow\) d, S \(\rightarrow\) b

I - volume constant → isochoric P → c

II - Adiabatic → Q → a

III - Temperature constant → Isothermal R → d

IV - Pressure constant → Isobaric S → b
