Thermodynamics Question 7

Question 7 - 2024 (31 Jan Shift 1)

The given figure represents two isobaric processes for the same mass of an ideal gas, then

(1) $P _2 \geq P _1$

(2) $P _2>P _1$

(3) $P _1=P _2$

(4) $P _1>P _2$

Show Answer

Answer: (4)

Solution:

$PV=nRT$

$V=\left(\frac{nR}{P}\right) T$

Slope $=\frac{nR}{P}$

Slope $\propto \frac{1}{P}$

(Slope $) _2>(\text { Slope }) _1$

$P _2<P _1$
