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!).
Ice cream melting (or pretty much anything melting) is an endothermic process in that it requires the absorption of heat energy in order to occur. An example of an exothermic â¦ process is the burning of paper which gives off heat energy.ce cream melting (or pretty much anything melting) is an endothermic process in that it requires the absorption of heat energy in order to occur.
