Question

In the V-T diagram shown in adjoining figure, what is the relation between p1 and p2? (A) p2 = p1 (B) p 2 < p1 (C) p 2 > p1 (D) insufficient data

In an isobaric process, p= constant Hence, V propto T i.e., V=((n R/p)) T ∴ V-T graph is a straight line with slope propto (1/p) According to given figure, (slope) 2>( text slope )1 ∴ p2 < p1

Q. In the $V - T$ diagram shown in adjoining figure, what is the relation between $p$ ₁ and $p$ ₂?

$p_{2} = p_{1}$

$p_{2} < p_{1}$

$p_{2} > p_{1}$

insufficient data

In an isobaric process, $p =$ constant
Hence, $V \propto T$
i.e., $V = (\frac{n R}{p}) T$
$∴ V - T$ graph is a straight line with slope $\propto \frac{1}{p}$
According to given figure, (slope) $_{2} > (slope)_{1}$
$∴ p_{2} < p_{1}$

Q. In the V−T diagram shown in adjoining figure, what is the relation between p1 and p2?

p2​=p1​

p2​<p1​

p2​>p1​
