What Property Of Matter Can Be Observed Without Changing The Identity Of The Matter? Physical properties, such as mass, volume, density, and color, can be observed without changing the identity of the matter. We can further categorize the physical properties of matter as either intensive or extensive. Intensive properties do not depend on the amount
What Are The Factors That Cause Matter To Change? Temperature can cause molecules to move slower or faster. Pressure can cause molecules to become more or less packed together. What are factors of matter? Temperature and pressure determine the state of a substance. A change in temperature or pressure will result in the change of
