It looks like you've uploaded an image of a worksheet titled
"PHYSICAL VS CHEMICAL CHANGE – IDENTIFYING CHANGE", which contains a list of 20 scenarios. The task is to determine whether each scenario describes a
physical change or a
chemical change.
Since I can't view images directly, I’ll need you to provide the text of the worksheet (the list of 20 items) so I can help solve and explain the answers.
However, if you'd like, I can guide you through how to identify physical vs. chemical changes:

🔍 How to Tell the Difference:
-
Physical Change: A change in form or state, but
no new substance is formed.
- Examples: melting ice, cutting paper, dissolving sugar.
- Reversible in many cases.
- No color change, no gas production, no precipitate.
-
Chemical Change: A change where
a new substance is formed.
- Indicators: color change, gas production, formation of a precipitate, temperature change, odor change.
- Often irreversible.

✔ Example:
1.
Melting ice → Physical (just changing from solid to liquid water)
2.
Rusting iron → Chemical (iron reacts with oxygen to form rust)

Please copy and paste the list of 20 items from the worksheet, and I’ll go through each one with explanations!
