Question

What is the value of compression factor Z for the gas?
(A) 1
(B) >1
(C) <1
(D) Zero

Answer 1

Answer:

a )1

Explanation:

at all temperature and pressure Z =1

Answer 2

Compressibility factor Z for gas = 1

Explanation:

The compression factor (Z) is a correction factor which describes the deviation of a real gas from ideal gas behaviour.

So by formula, we can write it as volume occupied by a real gas divided by volume occupied by an ideal gas, at the same temperature and pressure.

For an ideal gas the compressibility factor is Z=1 per definition.

The real gas behavior is different from the ideal gas behavior. So this factor helps us in studying the difference and it is an useful thermodynamic property.
