Question

The given figure represents Isobars drawn at constant pressure $P_1$ and $P_2$ , for an ideal gas. Which is correct?
.

• A. $P_1>P_2$
• B. $P_1<P_2$
• C. $P_1=P_2$
• D. All

Answer 1

Answer: (A)

$V=\frac{nRT}{P}$
Slope of $V$ $vs$ $T$ graph increases as pressure decreases.
Hence, $P_1>P_2$ .
