Quiz Study Guide Compounds, States of Matter, and Phase Changes Tuesday November 26th Multiple choice questions will cover the following topics: 1. Compounds- reading the formula. Can you tell us what elements and how many atoms of each element are found in common compounds? Example: H2O- contains elements hydrogen and oxygen. 2 atoms of hydrogen, 1 atom of oxygen, 3 atoms total in this molecule. 2. Three states of matter- how are the particles moving (fast, slow, close together, far apart) for the three states of matter? What shape and volume do each state of matter have? Example: Particles in a solid are close together and vibrate slowly 3. Phase Changes- What do we call each phase change? Look at your phase change pyramid. How do we get matter to change phases? What do the particles/molecules look like as they change phases? (Do the elements separate/stay together? Do the molecules move closer together and slow down or do they spread apart and speed up?) Example: Solid to a gas is called ___________ (sublimation) energy is being ______ (added) Quiz Study Guide Compounds, States of Matter, and Phase Changes Tuesday November 26th Multiple choice questions will cover the following topics: 4.
