Question:
A real gas behaves like an ideal gas if its?
Pressure and temperature are both low
Pressure is high and temperature is low
Pressure and temperature are both high
Pressure is low and temperature is high
Solution:
By real gas equation, (P + a/V²)(V - b) = RT
At High T, the gas molecules have a higher average kinetic energy (KEavg) which overcomes the IMF(Intermoleculer force). At Low P, the gas molecules are spread further apart and can therefore avoid IMF. So, pressure should be low and temperature should be high for the ideal gas behaviour
