1. Purpose: The purpose of this lab is to see the temperature change in

3. Procedures: Place 200 ML of water in a 250 ML beaker. With the
tongs gently place a colored ice cube into the water. Measure the
temperature after 1 and 2 minutes. In another beaker place 200 ML of
warm fresh water into the beaker adding enough salt to saturate the
water. Repeat this 3 times.

4. Conclusions: In my conclusions it says that the longer the water stays
in the cooler it gets. They were both pretty much the same in temp of the
salt and fresh water. Ice is always usually melted in 3 minutes.
