The first 5 mins is the tap water at room temperature and starts to boil to 100degrees, so the graph increases.
The second 5 mins, is a straight line graph as the beaker is boiling at 100 degrees.
The third 5 mins is when the beaker is left to cool hence the graph is a downward sloping to room temperature.
The last 5 mins is when the beaker is alr at room temperature hence it is constant at 25 degree.
