All matter on earth exists in one of three phases or states: solid, liquid, or gas. A substance's phase is determined by the speed of its molecular motion, often referred to as kinetic energy. Adding or removing heat energy from a substance can change it from one state to another. This course illustrates the types and properties of matter states, and concludes with a discussion of temperature scales and the different types of heat transfer.
•Match each phase of matter with its characteristics
•Describe the role of temperature in determining the phase of matter
•Describe how heat is measured
•Differentiate between the three ways that heat is transferred
