On a temperature versus time graph, how does the temperature at the beginning of a change of state compare with the temperature at the end of the change?

always lower

always the same

usually lower

usually higher

The change of state of matter occurs at the constant temperature, because the heat energy given to the matter is used to change the state in this condition.

So, in the beginning and at the end of the change, the temperature remains constant.

The graph between temperature and time is a straight line parallel to time axis as shown.
