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.
Mixing hot coffee with cold milk is a physical change because the molecules of both substances do not undergo a chemical reaction. The temperature change occurs due to heat transfer from the coffee to the milk, but the chemical composition of the coffee and milk remains the same.
Heating milk or cream will help prevent the dairy from curdling from the sudden temperature change. The milk or cream has fats and proteins that will react negatively when suddenly changing temperature very quickly. They need to be gently brought up to temperature to retain their consistency.
