What does “Real vs ideal gas behaviour” actually mean in States of Matter: Gases, and why does it matter for NEET?
real gases deviate from PV = nRT at high pressure and low temperature, when molecular size and attractions can't be ignored.
In simple words: real gases deviate from PV = nRT at high pressure and low temperature, when molecular size and attractions can't be ignored. Getting Real vs ideal gas behaviour clear matters because NEET questions on States of Matter: Gases usually test this idea directly, not just a formula you memorised.
Key point
Real vs ideal gas behaviour
Common mistake
assuming every gas obeys the ideal equation under all conditions.
Memory tip
ideal-gas law works best at low pressure and high temperature.
