Question

what is termed as compressibility factor (z) and show for ideal gas its value is 1

Answer 1

Answer: -

The compressibility factor is the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure.

It is the value Z = $\frac{P x V}{R x T}$

Here P = pressure, V = volume, R = universal gas constant and T is temperature.

But for an ideal gas, PV = nRT

So n = 1 for an ideal gas.

This means an ideal gas can be compressed infinitely.
