The atoms of a solid possess some certain min. zero point energy even at 0k, while no such restriction hold for the molecukles in an ideal gas. Use the uncertanity principle to explain these these statements. ok, so what i am thinking is the at 0k the atoms of a solid have some energy because if it did have not energy, we would know exactly the position and momentum of the atoms. so an ideal gas cannot reach 0k by definition becuase a gas is mostt ideal high temp and low desnities. if it were to reach 0k, it would turn into a soild. ????
