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.
Is mixing salt and water chemical?
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
Is mixing sugar in coffee a physical or chemical change?
Mixing sugar in a coffee is a physical change. Mixing sugar in coffee is a physical change because it does not form a new substance, it is still sugar and coffee. If you decided to mix sugar and water to make sugar water, the water could be left to evaporate and the sugar crystals would still be there. So mixing sugar in coffee is also very easy to reverse.

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.
Does Mixing a teaspoon of instant coffee with hot water is physical?

Is mixing a teaspoon of coffee into hot water a chemical or physical reaction?
Mixing a teaspoon of coffee into hot water is primarily a physical reaction. The coffee granules dissolve in the water, resulting in a solution, but no new substances are formed. This process involves the physical dispersion of the coffee particles rather than a change at the molecular level that would indicate a chemical reaction.
