Souring milk causes a chemical change because it changes its state of matter (from a liquid to a semi-solid), and it grows bacteria. When milk sours it causes a permanent change, therefore making it a chemical change.
Making ice cream from sugar and cream involves both chemical and physical changes. The mixing and freezing of the ingredients results in a physical change as the state of matter changes from liquid to solid. At the same time, the reaction between the sugar and cream, as well as any added flavorings, involves chemical changes that alter the composition of the ingredients.
No. It is purely a physical change, that of melting. No chemical reaction takes place.
The process of cream being whipped is a physical change. The cream changes from a liquid to a whipped, aerated form through physical means such as mixing and incorporating air, but its chemical composition remains the same.
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.
Physical change
It is a physical change.

no its a chemical change (i just did i project on making ice cream in meh class and one question was "is this a chemical or physical change? how do u know?"
Preparation of cream from milk is a physical process.
physical because a chemical change means it can never form back

physical; it changes only in appearance, not chemical structure :)

whipping cream is not a chemical change since the whipped cream can be dewhipped make into cream...all you are doing when you whip cream is mix air into the cream
lol i re-learned this 2day its a chemical change because it turns into something diffrent, (the texture, and temp it must be) and you cannot get the cream back. Hope i helped :)
