there are two changes in matter: physical change and chemical change. physical change means the change in size, shape, texture and any other physical characteristics, but no any new substance made or added. while in chemical change, there's a change in the object's physical appearance but also made a new substance.

Is reacts with acid to from H2 a phsical property or a chemical property?
Reacting with acid to form H2 is a chemical property, as it involves a change in the chemical composition of the substance. Physical properties, on the other hand, pertain to characteristics like color, density, and state of matter.
Is writing with pen a chemical change?
Writing with a pen involves a physical change rather than a chemical change. A chemical change involves the formation of new substances with different chemical properties, while in writing with a pen, the ink is simply transferred onto the paper without any chemical reactions occurring. The ink may undergo physical changes such as drying or adhering to the paper, but the chemical composition of the ink remains the same.
Why is breaking chalk a physical change?
Besides for rearranging the glass pieces, one is not actually changing the chemical formula of the glass. Much like grinding NaCl, the crystals get smaller but the chemical remains the same.
A change in matter that produces new substances is called?
Chemical change. References: Intro to Matter book.
Is shortening melting a chemical change or chemical property?
Shortening melting is a physical change, not a chemical change or chemical property. When shortening melts, it undergoes a change in state from solid to liquid without any change in its chemical composition.

Is boiling an egg chemical or phsical?
Boiling an egg is primarily a chemical change. When an egg is boiled, the heat causes the proteins in the egg white and yolk to denature and coagulate, resulting in a change in texture and structure that cannot be reversed. This transformation alters the egg's chemical composition, making it a chemical change rather than a physical one.
When boiling take place is the phase change a chemical or phsical change?
It is a physical change, the substance stay the same elements before and after the change, this is the same for all states of matter changes (melting, freezing, evaporating, condensing, and sublamation)
