If the temperature is below the decomposition temperature, then melting a physical change not chemical as the liquid sugar (or molten sugar) can be solidified again.

∙ 14y agoA glycosidic bond forming between two monosaccharide molecules to form a disaccharide via a condensation reaction in which one atom of hydrogen and one hydroxide ion (i.e. one molecule of water) are removed and the remaining oxygen molecule joins to one of the carbon atoms in the benzine ring of both monosaccharides. An example would be the joining of a molecule of fructose and a molecule of glucose together to form a molecule of sucrose.

- crush the sugar cube
- then add water

How is melting sugar different from melting an ice cube?
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
Who invented the sugar cube?
.jacob chistoph radinvented the sugar cube.
What is the difference between powder sugar and sugar cube?
ones a powder. other is pressed into a cube. your welcome
Is a well cooked steak chemical or physical change?
Cooking involve many chemical processes but also some physical processes as evaporation or melting.
What is physical change in matter?
A physical change is a change to a substance/object which can be easily reversed, and no new substance is formed from it (as opposed to chemical change). The state of matter is usually changed, for example, turning from a solid to a liquid. e.g. ice cube melting
When a sugar cube dissolves is it a chemical change?
No.

Melting sugar cube is what change because the substance still is sugar?
Melting a sugar cube is a physical change because the substance remains sugar, just in a different form (solid to liquid). The chemical composition of sugar does not change during the melting process.
Is a cube of surgar dissolving in water a physical or chemical change?
This is a physical change the chemical composition of the sugar does not change
Is a sugar cube is grounded up a physical or chemical change?
Physical.
If a sugar cube dissolves is it chemical change?
Dissolution is a physical process.
Is a sugar cube grounded up a chemical or physical change?
Physical.
What would react more quickly in a chemical reaction a single sugar cube or an equal mass of sugar crystals?
Granulated sugar. With a sugar cube, only the sugar on the six faces of the cube can react; the sugar WITHIN the cube is surrounded only by other sugar molecules. Ground-up, or "granulated" sugar has thousands of faces, so it can all react at once.
Is melting a sugar cube a chemical change?
Melting a sugar cube is a physical change because the sugar molecules do not transform into a different substance when heated, but only change from a solid to a liquid state. If the melted sugar were to further undergo a chemical change, such as caramelization or burning, then it would be considered a chemical change.

chemical
Is a solid that is crushed a chemical or physical change?
Nope. That is a physical change. a sugar cube that is crushed into powdered sugar is still sugar.
