Is digestion of a candy bar a physical change or chemical change?
Chemical property
When you had dissolve a candy in your mouth is that going to be a chemical change or a physical change?
Physical, because it's changing state.
Is melting a candy bar a chemical change?
Melting a candy bar is a physical change because it is just changing form, not changing the chemical makeup. (If it isn't making a new material, it is not a chemical change)
Is it a chemical or physical change when pop rocks pop in your mouth?
The pop that results is caused by the release of carbon dioxide bubbles that are encapsulated within the candy. This is a physical change, rather than a chemical reaction, because no new products are formed.
Is a volcano exploding a chemical or physical change?
This answer is complex. The short answer is both.In general, if you go from a liquid to solid state without a change in the chemistry of the compound you are merely changing physical state, not chemical. This is most easily observed with making ice cubes. Water freezes but it stays water and when you put the cubes in a glass of water you still have water when it melts. So the major change when lava hardens is a physical change.Lava however is not a uniform chemical compound like water. You can see this as lava hardens that it forms crystals in the rock. These crystals are also a physical change as compounds that are similar to one another fall out of solution and crystallize as the liquid rock cools, much the same way rock candy forms from a cooling solution of sugar and water. With rock candy this is still a physical process because you can reheat the rock candy in the water and it becomes a solution again.The complex part of the answer is that with lava gases are often given off, some of which are as a result of chemical reactions during the cooling process. When you remelt the same rock, the chemical solution you get is not exactly the same as what you started with. So some chemical changes are occurring during the overall physical change.For example, heat and cool baking chocolate over and over. Soon you get something you are not sure you really want to eat. This is because the chemical changes happening in each cycle are small enough to miss during one melt/cool cycle but repeating this process makes what is happening chemically more obvious.

Is cotton candy dissolving a chemical or a physical change?
:/
Is making a rock candy by evaporating water from a sugar solution a physical or chemical change?
physical
Is chewing a peppermint candy a physical or chemical change?
It is a state change from a solid to a liquid and so it is physical.
Is ice candy physical or chemical change?
chemical change,because the liquid form inside the ice candy plastic,changed into a solid particles and getting iced.

Is making ice candy physical or chemical change?
Physical change because the strawberry is still a strawberry and the chocolate is still chocolate.

Is Transparent rock candy is finely ground into an opaque white powder physical or chemical change?
Actually, it is a physical change because when sugar and water mix together, they are not forming a new substance, sugar dissolves, but it doesn't disappear. So when you crystallize it, it still has the same chemical structure, the only thing that changed is the physical appearance.
