Quizplus · Accepted Answer

Choice C shows the correct energy changes that occur in a beaker full of ice (system) as it warms up on a lab bench (surroundings). At the beginning, the ice absorbs heat from the surroundings, which Leads to endothermic ΔH. Then, as the ice melts, it absorbs more heat from the surroundings, which results in an endothermic ΔH of fusion. Finally, as the water reaches room temperature, It absorbs more heat from the surroundings, which Leads to an endothermic ΔH because the temperature increased. The other bar charts have incorrect labels or incorrect energy changes.
