Give an example of how you've seen the law of conservation of matter in action today.

Question

Since we don't know what "you've seen," it is impossible to answer this question. You need to review the law of conservation of matter in your textbook to compare your experiences.

However, I searched Google under the key words "law conservation matter" to get these possible sources:

I hope this helps. Thanks for asking.
