- The extensive property of matter is the property that does change as the matter changes such as volume and mass. Can matter change physically? A matter can go through a process to change its physical state. We can take water as an example here. As ice, water is a solid matter with a specific volume, mass, density, and color.

Physical Changes in Matter. A physical change in matter is a change in one or more of matter's physical properties. Glass breaking is just one example of a physical change. Some other examples are shown in Figure below. In each example, matter may look different after the change occurs, but it's still the same. An increase in temperature will cause which of the following to occur: answer choices. Water vapor in the air condensing to form clouds. Water in a lake freezing into solid ice. A balloon filled with air falling slowly to the ground. A solid bar of chocolate melting and changing shape.
