Kind of... if you boil milk, then some of it evaporates, so... sort of :)
Milk thickening is generally considered to be a physical change because it involves a change in the physical state of the milk without altering its chemical composition. Heating milk causes the proteins to denature and form a network that traps water molecules, resulting in a thicker consistency.
Yes, heating coconut milk until it turns into brown syrup is a chemical change. The heat causes the milk's proteins and sugars to undergo a series of complex reactions that lead to a change in its color, consistency, and flavor, creating a new substance with different chemical properties.
Adding cold milk to hot coffee is a physical change because the milk and coffee retain their original chemical properties after mixing. The change in temperature is a physical property of the substances.
Boiling milk is a physical change because it does not alter the chemical composition of the milk. The heat causes the milk to change from a liquid to a gas without changing its molecular structure.
Pouring milk into a glass is a physical change. This is because the milk remains the same substance (liquid milk) even after it is poured into the glass.

If it is a chemical change it will have a change in color (not meaning food coloring was added) precipitate (solid) was formed, release of gas, new substance was formed, temperature change. If something is baked it was a chemical change

This is a chemical change.
It's not a physical change
yes it is a physical change. there is no chemical change

The question to answer is "Has a new substance been created?" Most cdertainly heating does change the cheese, milk and eggs used in most mac and cheese recipes. So the answer is, yes, cooking mac and cheese is a chemical change.
Milk curdling is a chemical change.
Physical changes are those that do not alter the chemical composition of a substance. I hate to give out homework answers, but here's a push in the right direction: what in your kitchen could change a glass of water in a way that is reversible, and would not chemically alter it? Consider things like mixing with non-reactive substances and heating. There are many more that are probably within arm's reach.
