SECTION-A
For three low density gases 
pressure versus temperature graphs are plotted while keeping them at constant volume, as shown in the figure.
The temperature corresponding to the point ' 
' is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
From ideal gas equation
volume is constant
It is clear from graph that for all the gases lines of graphs meet at same value.
At 
-axis (temperature axis) 
is zero but temperature is negative and it will be equal to 
or
