Question
Hi! Due to another sibling arguement, my brother and I have come across a question that I'm dying to have answered. (and to be proved that I'm right, once again! ;p) We were wondering when dissolving a substance in a liquid, does it affect the temperature of the solution?  

Answer
For water, the majority of the time the solution will cool, sometimes stay the same, rarely get warmer.  For other liquids it will vary based on the liquid.  For water the change in temperature is small except in some rare cases.
