Explanation :

The heating curve shows how water changes from one state of matter to another based on temperature and the addition or removal of heat over time.

Initially, ice is heated until its temperature reaches [tex]0^0\ C[/tex] and changes to liquid state.

From the attached graph it is clear that until [tex]100^0\ C[/tex] the temperature will rise steadily. Here, the liquid begins to vaporize. Vaporization is the state of matter at which liquid state changes to the gaseous state.

So, E is the point which shows the gaseous state.

Answer:

According to the cooling curve given above, at temperature 275K, the phases that will be observed is LIQUID AND SOLID.

The flat points on the graph represent the points where phase changes are taking place.The beginning of the first flat point represent the point where the gas become liquid, the extreme end of this point indicate the point where the liquid has started turning to liquid and that is the point of 275K. Thus at that point both phases are present.
