For this I know that PE=W, and that 2mgh is proportional to the change in temperature, but for some reason I can't get the correct answer

2(1.5 g)(9.8 m/s2)(3.5m)=103 C, but this is not correct

What you calculated is the work done in Joules, not the change in temperature. But the temperature change is proportional to the work done, but proportional does not mean equal. The relationship is as follows:

[tex]W = c m \Delta T[/tex]

Where c is the specific heat of water (look it up) and m is the mass of the water.

[tex]W = c m \Delta T[/tex]

Where c is the specific heat of water (look it up) and m is the mass of the water.
