Question

Which are examples of physical changes occurring? (Select all that apply.)

Answer 1

Answer:

1, 2, 4,

A physical change changes the appearance of the subtsance but not its molecular structure. A chemical change will create a new substance, and therefore change the molecular structure. When baking bread, the yeast, heat, and water create a chemical reaction(which is why bread rises when it is baked) hope this helped.
