No. It is purely a physical change, that of melting. No chemical reaction takes place.
Melting (and freezing) is always physical.
Melting ice cream is a physical change because it has the ability to go back to it's frozen form and be ice cream again. The chemical identity of it isn't changed.
No, its a physical change. It make be changing from a solid to a liquid, but it is not changing at a chemical level, only at a physical level. No matter how you slice it, it is still ice cream (but maybe a little drippy).

They're objects, they're not a change of any sort.
Dissolving salt in soup is a physical change.

Fermenting cheese and grating cheese are chemical changes.
No
It is a physical change because it has not changed its chemical composition.

Making ice cream and then letting some of it melt are two examples of phase change.The freezing cold of the ice cream maker causes the liquid cream to give up its heat and turn solid. This freezing phase change is exothermic because energy (heat) comes out of the cream.If you leave a bowl of ice cream on the table in a warm room, the heat energy of the air will enter into the ice cream and it will become liquid. This melting phase change isendothermic.Memory tip:exo - the heat energy exits the cream, which gets colder.endo - the heat energy goes into the ice cream, which gets warmer.
