. The compressibility factor of an ideal gas is

Best Answer

The correct option is A.

The compressibility factor is the ratio of molar volume of a gas to the molar volume of an ideal gas. We know PV = n R T. For the compressibility factor of an ideal gas, it is measured at the constant temperature and pressure. Now, we know for an ideal gas, the factors like temperature, pressure, and volume are stored to be constant. So, we are able to say that if these types of factors are constant, then the quantity of moles of gas is too constant or equal to 1.
