Question

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

• A. Density of gas is increasing in graph (i)
• B. Density of gas is decreasing in graph (ii)
• C. Density of gas is constant in graph (iii)
• D. None of these

Answer 1

Answer: (C)

Density of gas is constant in graph (iii)

Answer 2

(i) At constant temperature P µ r

(ii) At constant pressure T µ $\frac { 1 } { \rho }$

(iii) V ® constant

\ r ® constant
