Compressibility factor of a gas is given by the equation `Z=(PV)/(nRT)`. On this basis , mark the correct statement.

Options

A. When Z `gt` 1 , real gases get compressed easily .
B. When Z = 1 real gases get compressed easily .
C. When Z `gt` 1 , real gases are difficult to compress .
D. When Z = 1 , real gases are difficult to compress .

Answer

C

Explanation

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