Chemistry Question on States of matter
When is the deviation more in the behaviour of a gas from the ideal gas equation pV = nRT?
A
At high temperature and low pressure
B
At low temperature and high pressure
C
At high temperature and high pressure
D
At low temperature and low pressure
Answer
At low temperature and high pressure
Explanation
Solution
Gases show deviation from ideal gas behaviour when the temperature is low and pressure is high.At low temperature, the volume of one molecule is not negligible in comparison to total volume and intermolecular force of attraction is maximum at low temperature and high pressure.
