A chemical change because the chemicals from the bee's stinger are reacting with the chemicals in your body, producing the red mark.
Pulverizing sugar is a physical change because it does not alter the chemical composition of the sugar molecules. Grinding the sugar only changes its physical state by breaking it down into smaller pieces without creating any new substances.
Adding sugar to cereal is a physical change because the sugar does not undergo a chemical reaction when mixed with the cereal. The sugar retains its chemical structure and properties, only altering the taste of the cereal.
It is a physical change as you can change it back.
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.
ANSWER:A physical change. Nothing new is made from the solution and they both can be separated later by using heat to evaporate the water, leaving the sugar behind.
Pulverizing sugar is a physical change because it does not alter the chemical composition of the sugar molecules. Grinding the sugar only changes its physical state by breaking it down into smaller pieces without creating any new substances.
Sugar crystallizing is a physical change because it involves rearranging the molecules of the sugar without changing their chemical composition.

its a chemical lol
This is a physical change the chemical composition of the sugar does not change
Chemical change.
Yes, dissolving sugar in water is a physical change. If you let the water evaporate, you the sugar will be left behind. Evaporation is a physical process, not chemical.-No, It is a Chemical change.
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.
