Question

Which statement correctly describes a physical change?

involves breaking and creating chemical bonds but not changing a phase

may involve a change in phase but does not involve a change in the molecular structure

may involve converting two or more substances into new substances

involves changes at the molecular level

involves energy transfer and change in color

Answer 1

Help? ;'(

Answer 2

I would think it would be B

Answer 3

I agree with taramgrant

Which statement correctly describes a physical change?

involves breaking and creating chemical bonds but not changing a phase: Breaking of chemical bonds would would not be a physical change but rather a chemical change.

may involve a change in phase but does not involve a change in the molecular structure.
I think this is probably the best answer, b/c molecular structure isn't changed.

may involve converting two or more substances into new substances; that's basically what happens in a chemical reaction.

involves changes at the molecular level; changes at the molecular level would imply a physical change.

involves energy transfer and change in color. Change in color yes, but energy transfer not too sure about that.

Answer 4

It is B. Anything that changes the molecular structure is chemical.
