Now that you have learned about how chemical and physical changes differ and how they relate to the conservation of matter, explain the different changes that occur. Type your answer in the space below.

Answer 1

A chemical change is a process in which one or more substances are changed into one or more new substances with different properties. This type of change involves a chemical reaction, which is a process in which atoms are rearranged to form new molecules. Examples of chemical changes include burning, rusting, and fermentation.

A physical change is a process in which the form or appearance of a substance is altered without changing its chemical composition. Examples of physical changes include melting, freezing, and evaporating.

The conservation of matter states that matter can neither be created nor destroyed, only changed in form. This means that the total amount of matter in a system remains constant, even though the form of the matter may change. In a chemical change, the matter is rearranged to form new substances, but the total amount of matter remains the same. In a physical change, the form of the matter is altered, but the total amount of matter remains the same.
