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)
