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.
Mixing sugar in coffee is a physical change because the sugar molecules remain chemically unchanged - they are only dispersed in the coffee. The properties of the sugar and coffee individually are not altered by the mixing process.
A physical change is one in which after the rxn. or process each constituent retains it's properties.
When we mix sugar and coffee, first of all they don't mix in each other... or in other words in that mixture sugar and coffee retain their respective properties. Moreover we can also separate the constituents from that mixture.
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, it is a physical change as the water could be left to evaporate and the sugar crystals would still be there.
no, it's not because the identity of the coffee isn't being changed. It's still coffee, right? Yes it is. A chemical change will only occur when the identity of the substance is being changed.
For example, the process of making the coffee is a chemical change, because the milk and coffee beans have changed. The milk isn't milk anymore and the coffee beans aren't coffee beans anymore. These two ingredients have went through a chemical change to become coffee, so this would considered a chemical change, but adding sugar is NOT a chemical change, in fact, it is a physical change.
That is a PHYSICAL CHANGE, seeing as the sugar can be filtered out of the coffee in the same state it was put in (and you could probably even remake it into a cube if you tried hard enough :P). There was no change in colour, and no heat, light or sound produced.
Physical change - the sugar is dissolved in water and forms an aqueous solution, but no chemical change occurs.

Is mixing coffee with hot water a physical or chemical change?
Mixing coffee with hot water is a physical change because the individual substances (coffee and water) retain their chemical identities and only the physical state of the coffee changes, dissolving in the water. No new substances are formed.
Is stirring milk into hot coffee a chemical change?
No, stirring milk into hot coffee is a physical change. The milk and coffee remain the same substances they were before mixing, only their physical state has changed.
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 coffee plus cream a physical or chemical change?
Mixing coffee and cream is a physical change because it does not alter the chemical composition of either substance. The coffee and cream can be separated back into their original forms without any chemical reactions taking place.
Is mixing coffee with hot water a physical or chemical change?
Mixing coffee with hot water is a physical change because the individual substances (coffee and water) retain their chemical identities and only the physical state of the coffee changes, dissolving in the water. No new substances are formed.
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?
Yes, mixing a teaspoon of instant coffee with hot water is a physical change. It is a reversible change where the coffee dissolves in the water but can be separated by evaporation or filtration.
Is stirring milk into hot coffee a chemical change?
No, stirring milk into hot coffee is a physical change. The milk and coffee remain the same substances they were before mixing, only their physical state has changed.
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 coffee with hot water a physical change?
no
Is mixing salt and water a chemical change or physical?
Physical
Is mixing NaCi with another chemical a physical or chemical change?
It depends on what you are mixing it with.
Is mixing popcorn steam a physical or chemical change?
it is a chemical change
Is mixing chalk with water a physical change or chemical change?
physical :)
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 drink mix into water physical change or chemical change?
both chemical and physical
