a physical change
Dissolved in water containing coffee, not in coffee.
Physical
A mixture, specifically a homogeneous mixture called a solution.

okay let's say your putting sugar into coffee the solute is the sugar and solvent is the coffee. The Solvent coffee dissolves the solute "sugar" homogeneously amongst the solution. So the answer to your question is the solvent does the dissolving
Dissolving dissolving! Watch your grammar. The best example is sugar cube dissolving in a water. Best way to dissolve it is to smash it, put it in water and then stir it.
a chemical reaction
No, dissolving sugar in coffee is a process of solvation, not osmosis. Osmosis involves the movement of water molecules across a semi-permeable membrane to equalize the concentration of solute on both sides, which is not happening in this scenario.
The coffee remains coffee, and the sugar is simply dissolved. Thus, it is a physical change.
Sugar dissolving in water. Salt dissolving in water. Oil not dissolving in water. Ethanol dissolving in water. Carbon dioxide dissolving in soda.
It is a physical change.
yes dissolving sugar in a coffee is a physical change in a chemical change a new substance will be formed, and the component of this substance will be different from the parent substance. but in the case of sugar dissolving in coffee, mixture of sugar and coffee retain their respective properties. Moreover we can also separate the constituents from that mixture.and there is no new substance is formed
