Hi This question has baffled me, help me understand the correct answer. It's a graph question and i don't know whether i can post a graph here but this is the link to the paper.

Start by drawing a vertical line at t = 3 1/2 minutes.
Draw a straight line that passes through all the points between t = 0 and t = 3 1/2 minutes. This will be a horizontal line corresponding to the initial temperature of the solution.
Now draw a straight line through all the points from the 5 minute mark to the 12 minute mark, as these points lie in a straight line. Extend this line back as far as the vertical line at t = 3 1/2 minutes. The point at which this extended line meets the vertical line at t = 3 1/2 minutes corresponds to the extrapolated maximum temperature.
The difference between your extrapolated maximum temperature and initial temperature will be your temperature rise.
