Are drops of cold milk added to hot coffee a chemical or physical change?
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.
If you add hot coffee to cold milk is that a chemical or physical change?
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.
Why do we heat the milk or cream before adding to the cream soup?
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.

Is souring milk a physical or chemical change Why or why not?
It's a chemical change. The smell is the giveaway; a smell that wasn't there before is often an indicator of a chemical change. Also, the rate at which the milk sours can be changed by heat. For example, milk in the refrigerator is actually undergoing this souring reaction at all times, but the lower temperature inside the refrigerator slows it down so that it takes many days. But if you leave it outside the refrigerator, it will sour much more quickly - in a matter of hours. An increase in heat, therefore, quickens the reaction rate. This would not be the case in a physical change.
Is curdling of milk is physical change or chemical change?
Milk curdling is a chemical change.
