(i) At constant temperature P propto ρ (ii) At constant pressure T propto (1/ρ ) (iii) V arrow constant ∴ ρ arrow constant

Q. Pressure versus temperature graphs of an ideal gas are as shown in figure. Choose the wrong statement

density of gas is increasing in graph (i)

density of gas is decreasing in graph (ii)

density of gas is constant in graph (iii)

none of these

(i) At constant temperature $P \propto ρ$
(ii) At constant pressure $T \propto \frac{1}{ρ}$
(iii) $V \to$ constant
$∴ ρ \to$ constant

Q. Pressure versus temperature graphs of an ideal gas are as shown in figure. Choose the wrong statement

density of gas is increasing in graph (i)

density of gas is decreasing in graph (ii)

density of gas is constant in graph (iii)

none of these

(i) At constant temperature P∝ρ (ii) At constant pressure T∝ρ1​ (iii) V→ constant ∴ρ→ constant

(i) At constant temperature $P \propto ρ$
(ii) At constant pressure $T \propto \frac{1}{ρ}$
(iii) $V \to$ constant
$∴ ρ \to$ constant
