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 deviation of real gas from ideal behaviour in terms of compressibility factor , Z ?

Options

A. As the temperature increases , Z approaches a value close to one and gas starts behaving ideally .
B. Z continuously decreases with increase in pressure .
C. Z continuously increases with increase in pressure .
D. At high pressure , every gas has value Z = 1.

Answer

A
