Solid, liquid, gas, and plasma are all around us. But what makes a solid a solid or a liquid a liquid? This unit will teach you about the four most common states of matter and how kinetic energy drives the process of phase change.
Learning Objectives:
- Students will know that changes in states of matter are caused by different rates of movements in atoms.
- Students will know that variations in temperature and pressure can affect changes in states of matter.
Students Will:
- explain how the Kinetic Theory applies to states of matter.
- be able to explain the differences between solids, liquids, gasses, and plasma
- be able to explain how energy affects a matter’s state.
- be able to accurately identify the type of phase change that is taking place based on whether heat is being added or removed.
- be able to explain how pressure affects a matter’s state.
- be able to explain how temperature affects a matter’s state.
- be able to read and create graphs that show how pressure and temperature affect states of matter.
- know how graphs can help them better understand the effects of temperature and pressure on states of matter.
