Hello, A physical change describes a change that does physically and does not display “chemical” signs which are signs that indicate a precipitate being formed, change in color, density, or producing gas, etc. “Tearing a piece of paper in half” is a physical change because like I said earlier it doesn’t show any chemical change signs. I hope this helps you out!
Tearing a piece of paper in half is a physical change.
Explanation:
A physical change is a change in which the molecular composition of the subject does not change. Since tearing a paper in half does not cause a change in the molecules of the paper, it is a physical change.
