Consider the equation \( \mathrm{Z}=\frac{\mathrm{PV}}{\mathrm{RT}} \). Which of the following statements is correct?
(1) When \( Z>1 \), real gases are easier to compress than the ideal gas.
(2) When \( Z=1 \), real gases get compressed easily.
(3) When \( Z>1 \), real gases are difficult to compress.
(4) When \( Z=1 \), real gases are difficult to compress.
