Following on from my previous post on this forum, I did mean to write 25 ml of WATER, not salt.

We were doing a similar experiment, however, our group chose ammonium nitrate as the salt to be tested. We also used 25 ml of salt, but we tested between 2 and 6 grams of salt. We repeated each test 2 times, unless the 2 results were more than 0.5 degrees celsius apart, in which case, we did 3 tests. Here are our results: 2g: 1: 26-22-4 2: 26-22-4 3g: 1: 23-17-6 2: 22.5-16-6.5 4g: 1: 22.5-14-8.5 2: 21.5-14-7.5 3: 21-14-7 5g: 1: 21-12-9 2: 21-13-8 3: 21-12-9 6g: 1: 20-10-10 2: 20.5-10-10.5
