Tanya and James are working together on an experiment in their science class. They are instructed by their teacher to place a beaker full of water over a flame and take temperature readings each minute while it heats for 7 minutes. The graph of their results is shown below.

- What was the temperature of the water at 2 minutes?
- How did you find the temperature at 2 minutes from the graph?
- What was the temperature of the water at 3 minutes?
- How did you find the temperature at 3 minutes from the graph?
