Question

Above the Boyle temperature, the compressibility factor of the real gases, $Z$ is

• A. $1$
• B. $< 1$
• C. $> 1$
• D. $\le 1$

Answer 1

Answer: (C)

$> 1$

Answer 2

The temperature at which a real gas obeys ideal gas law over an appreciable range of pressure is called Boyle temperature or Boyle point. Boyle point of a gas depends upon its nature. Above their Boyle point, real gases show positive deviation from ideality and $Z$ values are greater than one. $Z > 1$
