Solution


Q.

Thermodynamic processes are indicated in the following diagram.            [2017]

Match the following.

  Column-1   Column-2
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  

Ans.

(1)

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
