When you use ice to cool the ingredients for ice cream, the energy is absorbed from the ingredients and from the outside environment (like your hands, if you are holding the baggie of ice!).
When something gets hotter it absorbs energy, and when it gets colder it loses energy. Because ice is very cold, it doesnât have much energy. When cream touches ice, energy in the form of. heat. flows from the cream to the ice. In other words, the cream gets colder and the ice melts.
