Question

As the pressure approaching zero i.e., at very low pressure, the curves plotted between compressibility factor Z and P for n mole of gases have the following characteristics.

I. The intercept on the y-axis leads to a value of unity.
II. The intercept on the y-axis leads to a value of 'n'.
III. The curves posses the same slope for different gases at the same temperature.
IV. The curves posses different slope for different gases at the same temperature.
V. The curves posses the same slope for gas at different temperatures.

Solution

The correct option is A I, IV, V
As we know,
compressibility factor is $Z (P V / n R T)$ .
from figure it can be seen that,
At very low P or P0,Z=1.
and curves posses different slope for different gases at same temperature.
