Changes of matter to make bubble gum?

The process of making bubble gum involves several physical changes and one chemical change. Here are the main changes that occur:

1. Mixing Ingredients:

> - Initially, the ingredients for bubble gum, such as gum base, sugar, corn syrup, and flavorings, are mixed together. This is a physical change as the ingredients are combined without any chemical reactions occurring.

2. Heating and Cooking:

> - The mixture is heated and cooked to dissolve the sugar and corn syrup. As the temperature rises, the sugar and corn syrup melt and form a liquid. This is another physical change as the state of the ingredients changes from solid to liquid without altering their chemical composition.

3. Cooling:

> - After cooking, the mixture is cooled to a lower temperature. This causes the liquid mixture to solidify and become chewy, forming the gum base. This change is also physical, as the state of the mixture changes from liquid to solid.

4. Addition of Flavor:

> - During the cooling process, flavorings are added to give the gum its desired taste. This is a physical change as the flavors are mixed into the gum base without undergoing any chemical reactions.

5. Kneading and Stretching:

> - The cooled gum base is then kneaded and stretched to improve its texture and elasticity. These processes involve physical changes as the gum base is manipulated without altering its chemical structure.

6. Blowing Bubbles:

> - When a piece of bubble gum is chewed and stretched, it becomes soft and pliable. Blowing air into the gum creates a bubble. This is a physical change as the gum undergoes temporary deformation without any chemical changes.

7. Solidifying the Bubble:

> - As the bubble is held in place, the gum cools and solidifies, trapping the air inside. This change is also physical, as the state of the gum changes from a stretched and inflated state to a solid bubble.

8. Chemical Reaction during Chewing:

> - Chewing the gum involves physical changes such as breaking down the gum into smaller pieces and releasing flavor. However, there is also a minor chemical change that occurs during chewing. The enzymes present in saliva begin to break down some of the ingredients in the gum, leading to a slight change in its chemical composition.

Overall, the process of making bubble gum involves a series of physical changes, such as mixing, heating, cooling, kneading, stretching, blowing, and solidifying. There is also a minor chemical change that occurs during chewing due to the action of enzymes in saliva.
