हिन्दीThermodynamics processes are indicated in the following diagram. Match the following: Column-I p. Process I q. Process II r. Process III s. Process IV Column-II a. Adiabatic b. Isobaric c. Isochoric d. Isothermal Options: (A) \( p \rightarrow a,\; q \rightarrow c,\; r \rightarrow d,\; s \rightarrow b \) (B) \( p \rightarrow c,\; q \rightarrow a,\; r \rightarrow d,\; s \rightarrow b \) (C) \( p \rightarrow c,\; q \rightarrow d,\; r \rightarrow b,\; s \rightarrow a \) (D) \( p \rightarrow d,\; q \rightarrow b,\; r \rightarrow a,\; s \rightarrow c \)
Correct answer · Option 3
\( p \rightarrow c,\; q \rightarrow d,\; r \rightarrow b,\; s \rightarrow a \)
Explanation
In a P-V diagram, slope for adiabatic is steeper than isothermal. I is isochoric (vertical, \( V=\text{const} \)), II is isobaric (horizontal, \( P=\text{const} \)), III is isothermal, and IV is adiabatic.
