Which system has the higher entropy? (a) A clean kitchen or a dirty kitchen? (b) A blackboard with writing on it or a completely erased blackboard? (c) 1 g of ice at 0 ° C or 10 g of ice at 0 ° C ? (d) 1 g of ice at 0 K or 10 g of ice at 0 K ? (e) 10 g of ethyl alcohol, C 2 H 5 OH , at 22 ° C (roughly room temperature) or 10 g of ethyl alcohol at 2 ° C (the approximate temperature of a cold drink)?
