Which best represents a physical change?

Chemistry
1 answer:
Zinaida [17]3 years ago
4 0

Answer:

The answer I would go with is A formation of a new substance.

Explanation:

This is because physical change includes changes of state. Some could be changing from a liquid to gas or solid to gas. B is not even an answer that should be considered because it doesn't fit into the category. C and D represents some of the examples of the process of physical change. Like boiling, bubbling, melting, or freezing. So the best would be A.
