In this article I learned that physical properties are used to observe and describe matter. This article told me about the different kinds of physical changes such as melting point and boiling point. Melting point is when an object is heated and turns into a liquid. Boiling point is when a liquid is heated and turns into a gas or vaporizes. This website supports what we are learning in science because we are learning about the different types or physical changes like melting point and boiling point.
