Boyle's temperature or Boyle point is the temperature at which a real gas starts behaving like an ideal gas over a particular range of pressure. A graph is plotted between compressibility factor Z and pressure P.

What is the variation of Z with pressure ?

Options

A. At very low pressures , all gases show Z = 1 .
B. At high pressures , all gases show Z gt 1 .
C. At intermediate pressures , most gases show Z lt 1.
D. All of the above .

Answer

D
