My daughter, in fifth grade, was asked to do an experiment measuring the 
effect of adding magnesium sulfate to water.  Obviously, it lowered the 
water temperature because the water lost heat energy.  My question is why 
did the water lose heat energy with the addition of magnesium sulfate?  I 
did a search for these terms but only came up with one article and it did 
not directly answer this question
