Adding cream to coffee is a chemical or physical change?

Adding cream to coffee is a physical change. Here's why:

* No new substances are formed: The cream and coffee simply mix together. They don't react chemically to create something entirely new.

* The change is reversible: You can separate the cream from the coffee by using a filter or allowing the mixture to sit for a while.

* The chemical composition remains the same: The molecules of cream and coffee don't change their structure when mixed.

Therefore, adding cream to coffee is a physical change because it involves a change in the appearance and physical properties of the mixture, but not the chemical composition of the ingredients.
