A gas will approach ideal behavior at
Low temperature and low pressure
Low temperature and high pressure
High temperature and low pressure
High temperature and high pressure
C.
High temperature and low pressure
For a gas to show ideal behaviour, the attractive force between the gas molecules must be negligible. At high temperature and low pressure, the attractive forces between the gas molecules becomes negligible.
