The other part of the test was the difference between chemical and physical process and characteristics. I attached a quiz here for you guys to test your knowledge on chemical and physical changes. Good Luck!
First Matter Quiz
Today we took a quiz over forms of matter and significant numbers. It was an easy test, but I personally strongly dislike significant numbers. The process defeats the purpose of all rounding rules I have ever learned. It makes no sense to me why this system would be used. I understand that it is supposed to help with accuracy, but some of the rules call for very inaccurate number values.
