Let's categorize each of the processes you mentioned as either a physical change or a chemical change:
1. **Baking cookies**: This is a **chemical change**. The ingredients undergo chemical reactions due to heat, transforming into a new substance (cookies) with different properties.
2. **Melting ice cream**: This is a **physical change**. The ice cream changes state from solid to liquid, but its chemical composition remains the same.
3. **Glass shattering**: This is a **physical change**. The glass changes shape and is broken into smaller pieces, but the material itself (glass) does not change chemically.
4. **Vinegar and baking soda combined forming bubbles**: This is a **chemical change**. The reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) produces carbon dioxide gas, resulting in bubbling and the formation of new substances.
In summary:
- Baking cookies: Chemical change
- Melting ice cream: Physical change
- Glass shattering: Physical change
- Vinegar and baking soda reaction: Chemical change
