# Ice cream experiment

I need need. I did the experiment, but I cannot answer the questions. Can anyone help?

How does the sugar affect the ice cream mixture?

How does the salt affect the ice bath? I believe it lowers the temperature.

Compare the affects of the salt and the sugar on their respective solutions?

What does Newton's Third Law of Thermodynamics say? Could not find this anywhere.

Thanks so much

Hint: try an experiment where you add sugar to "freezing" cream. Measure the temperature, before and after adding sugar. (you may want to add a larger amount of sugar than you might ordinarily use in ice cream)

How does the salt affect the ice bath? I believe it lowers the temperature.
Correct.. the salt does depress the freezing point ice/water bath.. I have noticed (subjectively), in making ice cream, that the more salt I add, the quicker it depresses the freezing point and seems to make "smaller" ice crystals in the ice cream.

Compare the affects of the salt and the sugar on their respective solutions?
based on the answers you have found out for the previous two questions
you should be able to formulate your own answer on this one.
