Question

Following figure shows $P-T$ graph for four processes $A,B,C$ and $D$. Select the correct alternative.

• A. $A$ - Isobaric process
• B. $B$ - Adiabatic process
• C. $C$ - Isochoric process
• D. $D$ - Isothermal process

Answer 1

Answer: (C)

(A) Temperature is constant $-$ isothermal
(B) Pressure is constant - Isobaric
(C) Pressure $\propto$ Temperature - Isochoric process
(D) $P^{1-\gamma }{T}^{\gamma }=$ constant $-$ Adiabatic process
