GasesIdeal Gas Model and Liquefaction53Choose the best answerAn ideal gas cannot be liquefied in the ideal-gas model because:AIts critical temperature is always above 0°CBIt solidifies firstCIts particles are very largeDIntermolecular attractive forces are assumed to be absent Like 0 Discuss 0Share
GasesFree Expansion of an Ideal Gas54Choose the best answerAn ideal gas undergoes free expansion into a vacuum. Its temperature does not decrease because ideal-gas molecules:AAre always above the inversion temperatureBHave no intermolecular attractive forcesCLose kinetic energy during collisionsDPerform maximum external work Like 0 Discuss 0Share
