Consider heating solid water (ice) untii it becomes quid and then gas (steam) (Fgure.1). How much heat energy, in kilojoules, is required to convert 64.0g of ico at 18.0C to water at 25.0C ? A Aernatively, consider the reverse process, cooling Express your answer to three significant figures and include the appropriate units. beam until it beomes water and, finally, ice ( igure. 2). In each case, two types ol transitions occur, those involving a temperature change with no chango in phase (shown by the diagonal line segments on the graphs) and those at constart temperature with a change in phase (shown by horizontal line segments on the graphs).
