In this experiment I learned that the hot water will affect much more the tea bag than the cold water. When I put the tea bag in the cold water there is not much of a reaction. The tea bag stays there, it floats. After 2 minutes the particles starts coming out of the bag and we can see more the reaction. In the hot water we can see the reaction in the same instant. The tea bag sinks and the particles go out much faster because of the heat energy.
