Answer 1

The compressibility factor (Z), also known as the compression 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.

because Z = V(real) / V(ideal)

so if Z >1 then V(real) > V(ideal)

It shows that real gas takes up more volume compare to ideal gas. Force of attraction between the gas particles of gas is less compare to the force of attraction between the gas particles of ideal gas.We can also say that real gas has less density compare to ideal gas.

because Z = V(real) / V(ideal)

so if Z <1 then V(real) < V(ideal)

It shows that real gas takes up lesser volume compare to ideal gas. Force of attraction between the gas particles of gas is more compare to the force of attraction between the gas particles of ideal gas, we can also say that real gas has more density compare to ideal gas.
