When $Z > 1,$ real gases are difficult to compress

(C) The deviation from ideal behaviour is expressed by the compressibility factor $Z.$ $Z$ is defined as $Z = \frac{PV}{nRT}.$ For an ideal gas,$PV = nRT,$ so $Z = 1.$ When $Z > 1,$ the gas shows positive deviation from ideal behaviour. This implies that the gas is less compressible than an ideal gas,meaning real gases are difficult to compress compared to ideal gases.
