Lesson: States of Matter Physics

Students will be able to

• recall that there are three states of matter that are common on Earth: solid, liquid, and gas,
• recall that liquids and gases are both fluids,
• describe what is meant by the terms melting, condensing, freezing, solidifying, boiling, evaporating, and sublimating,
• recall that when a substance is not undergoing a state change, a change in its internal energy will result in a change in temperature,
• recall that when a substance is undergoing a state change, a change in its internal energy will not result in a change in temperature,
• interpret graphs and tables of temperature against time for substances and identify the temperatures at which state changes occur,
• describe in approximate terms how particles are arranged in solids, liquids, and gases.
