Heat and Thermal ExpansionHard
Question
Pressure versus temperature graphs of an ideal gas are as shown in figure. Choose the wrong statement :-
(i)
(ii) 
(iii) 
(i)
(ii) (iii) Options
A.Density of gas is increasing in graph (i)
B.Density of gas decreasing in graph (ii)
C.Dencity of gas is constant in graph (iii)
D.None of these
Solution
For equation :
At constant temperature
For 1st graph : ρ ∝ P At constant temperature.
For 2nd graph :
For equation :
At constant P, ρ ∝
For 3rd graph L. :
= constance ⇒ P ∝ T⇒ density = ρ constant
