2 and 4

Answer 1

What’s the answer

Answer 2

To determine which changes are physical changes, I'll need to know the specific changes listed in your table (1, 2, 3, 4). Physical changes typically involve alterations in state or appearance without changing the substance's chemical composition, such as melting, freezing, dissolving, or breaking. If you provide me with the information for the changes in your table, I can help identify which ones are physical changes!

Answer 3

I apologize for the confusion, but without specific details about the changes represented by numbers 1, 2, 3, and 4 in your table, I can't definitively tell you which ones are physical changes.

Please provide the descriptions of each change, and I'll help you identify which are physical changes!
