(a) Two55 g ice cubes are dropped into300 g of water in a thermally insulated container. If the water was initially at 25°C, and the ice came directly from a freezer at -15°C, what will be the temperature of the drink when the ice and water reach the same temperature? (Neglect the heat capacity of the glass.)
(b) Suppose that only one ice cube had been used in (a); what would-be the final temperature of the drink?
