Real gases show deviation from ideal behavior at low temperature and high pressure.

A real gas deviates most from ideal behaviour at

Assertion : For a certain fixed amount of gas the product PV is always constant Reason : Real gases deviate from ideal behaviour of low pressure and high temperature

For ideal gases, Z = 1 at all temperature and pressure.

A: A real gas will approach ideal behaviour at high temperature and low pressure. R: At low pressure and high temperature z = 1, for all gases

The real gases show deviations from ideal gas behaviour. It is observed that real gases donot follow Boyle's law, Charles law and Avogadro law perfectly under all conditions. The deviations from ideal behaviour can be measured in terms of compressiblity factor Z. (a)what is meant by the term Compressiblity ? (b) What is the value of Compressibility factor for ideal gases and real gases ?

Any gas shows maximum deviation from ideal gas behaviour at

Which of the following gases always show positive deviation from ideal behaviour with increase in pressure ?

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressure and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas behaviour as compared to the gases which are liquified with difficulty. Gas deviates from ideal gas behaviour because molecules

The deviation are maximum under high pressure and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas behaviour as compared to the gases which are liquified with difficulty. The van der Waals equation reduces itself to ideal gas equation at
