Question

Compressibility factor of a gas is given by the equation Z = (PV/nRT). On this basis, mark the correct statement. (A) When Z > 1, real gases get compressed easily. (B) When Z = 1 real gases get compressed easily. (C) When Z > 1, real gases are difficult to compress. (D) When Z = 1, real gases are difficult to compress.

When Z > 1, real gases are difficult to compress because the forces of attraction between the molecules are very feeble.

Q. Compressibility factor of a gas is given by the equation Z=nRTPV​. On this basis, mark the correct statement.
