Questions  

The figure below shows the plot of PVnT versus P for oxygen gas at two different temperatures. Read the following statements concerning the curves given below and identify correct statements.


(i) The horizontal line corresponds to the ideal gas
(ii)  T1>T2
(iii) The value of PVnT at the point where the curves meet on the y-axis is the same for all gases
 

a
Only (i)
b
Only (i) and (ii)
c
All of these
d
(ii) only

detailed solution

Correct option is C

For any gas,  PVnT=R=constantFor high temperatures, real gases show behaviour closer to ideal gas. Hence, T1>T2 .

Two identical containers A and B have frictionless pistons. They contain the same volume of an ideal gas at the same temperature. The mass of the gas in A is mA and that in B is mB. The gas in each cylinder is now allowed to expand isothermally to double the initial volume. The change in the pressure in A and B, respectively, is Δp and 1.5Δp. Then
