. When is deviation more in the behavior of a gas from the ideal gas equation


PV = nRT ?

(a) At High Temperature and low pressure

(b) Atlow temperature and high pressure

(c) At High temperature and high pressure

(d) At low temperature and low pressure

 

Best Answer

Correct Option is: (b)

There is more deviation in the behavior of a gas from the ideal gas equation PV = nRT at low temperature and high pressure.

At low temperature, both P and V are small. Hence, both pressure and volume corrections are appreciable. Due to this, the deviations are more pronounced.

At high pressure, the volume is quite small and the term b cannot be neglected in comparison to V.
