Is milk thickening a chemical or physical change?
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.
Is chemical change does heating of coconut milk til its brown syrup?
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.

Is mixing milk and lemon juice chemical or physical change?
Mixing milk and lemon juice results in a chemical change. The acidity of lemon juice causes the proteins in milk to denature and coagulate, leading to curdling. This process alters the composition of the milk, producing new substances like curds and whey. Thus, the change is not reversible, indicating a chemical transformation.
