Answer 1

physical change is the answer of this question

Answer 2

Answer:

Stretch in a rubber band is a physical change since there is a change in form or size. The correct answer is B.

Explanation:

• The appearance or shape of the matter changes due to a physical change, but the kind of matter in the material does not. A chemical change, on the other hand, modifies the kind of matter and creates at least one new substance with new attributes.

• Physical changes do not need the generation of energy. whereas chemical transformations often require the generation of energy (which can be in the form of heat, light, sound, etc.)
• Physical changes are reversible and do not result in the formation of new material. Chemicals produce a new material, which cannot be reversed.
