1.	Some subtances posses some residual entropy even at absolute zero. This is because
Answer» they contain some impurities they attain different orientationsof moleculeseven at ABSOLUTE zero it is DIFFICULT to attain absolute zero of temperature all the above FACTORS are responsible Solution :The residual ENTROPY at absolute zero is due to different ORIENTATION of the molecules even at absolute zero.
