a pysical bc it dont change the substance but yes the apearance
When sugar dissolves in hot water, it is a physical change. This is because the sugar molecules are simply mixing with the water molecules but are not undergoing a chemical reaction to form new substances.
No, the dissolving of sugar in warm water is not a chemical change; it is a physical change. When sugar dissolves, it breaks down into its individual molecules, but its chemical structure remains unchanged. This process is reversible, as the sugar can be recovered by evaporating the water.
The dissolving of a sugar cube in water is a physical change, not a chemical change. This is because the sugar molecules are still present in the water; they have not undergone a chemical reaction to form new substances.
The dissolving of sugar in hot water is a physical change because it does not alter the chemical composition of either the sugar or the water. The sugar molecules are merely dispersed throughout the water molecules.

Dissolution is a physical process.

It is a physical change as you can change it back.

When sugar dissolves in water, it forms a homogeneous solution, with sugar molecules (sucrose) dispersed throughout the water molecules. The process is a physical change, not a chemical reaction, and involves the breaking of intermolecular forces between the sugar molecules, allowing them to mix with the water molecules.
No, the dissolving of a sugar cube is a physical change, not a chemical change. The sugar molecules are still the same chemically; they are just dispersed in water instead of being in a solid form.

sugar dissolves in water.
Mixing sugar and water together is a physical change because it does not alter the chemical makeup of either substance. The sugar molecules simply disperse within the water molecules, forming a homogeneous mixture without forming any new chemical bonds. This process can be easily reversed by evaporating the water to retrieve the sugar.
There is no new product being formed, eg. its just sugar plus water. It's not like a new substance is being formed. For example a chemical change could be Iron and oxygen, which forms something new, which is Iron Oxide. Get it?? :)
