  1. 2. A scientific instrument used to measure atmospheric pressure.
  2. 5. ____ Gas Law combines Boyle’s, Charles’ and Avagrado’s Laws to form PV=nRT.
  3. 11. The law of ________ states that the volume of gaseous reactants and products are always in simple ratios of whole numbers, (if they're measured at the same temperature and pressure.) **
  4. 14. A group of atoms bonded together. The atoms can be the same or different. Over 100 million are known.
  5. 15. A unit of measurement that represents a number of molecules at a given pressure and temperature.
  6. 17. 273K, 101.325kPa
  7. 20. The measure of hot/cold.
  8. 21. The combination of Boyle’s and Charle’s law creates this law, used to find the relationship between volume, temperature, and pressure. ***
  9. 24. Millimeters of ______, used to show atmospheric pressure.

  1. 1. The amount of space a substance takes up.
  2. 3. The SI base unit of temperature, used in gas law equations.
  3. 4. Measurement of pressure x 1000.
  4. 6. The volume that one mole of gas occupies.**
  5. 7. The measure of temperature found in the metric system.
  6. 8. The amount of a substance. **
  7. 9. A property of gas meaning that there are few molecules taking up a given volume. **
  8. 10. A law that states as the pressure of a gas increases, volume decreases proportionally (if the amount of gas and temperature stay constant.) **
  9. 12. A law that states as temperature increases, the volume of a gas increases proportionally (if pressure and amount of gas stay constant.)**
  10. 13. One of these is equal to 101.325kPa
  11. 16. ________ Theory is the classical model which describes the behaviour of gases. **
  12. 18. 298K, 101.325kPa
  13. 19. A unit of volume in the metric system which can be used to calculate gas laws.
  14. 22. __________’s theory demonstrates that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules
  15. 23. A property of gas is defined as a volume change resulting from a pressure change.
