Question

In the given (V - T) diagram, what is the relation between pressures ${P}_{1}and{P}_{2}?$

Moderate

Solution

According to ideal gas equation

PV = nRT

Or $V=\frac{nRT}{P}$

For an isobaric process, P = constant and $V\propto T$

Therefore, V - T graph is a straight line passing through origin. Slope of this line is inversely proportional to P.

In the given figure,

${\left(Slope\right)}_{2}>{\left(Slope\right)}_{1}\phantom{\rule{0ex}{0ex}}\therefore \text{\hspace{0.17em}\hspace{0.17em}}{P}_{2}{P}_{1}$
