Across
- 4. Gases and liquids that have the ability to flow and take the shape of their container
- 7. States that the volume of a gas, maintained at a constant temperature and pressure, is directly proportional to the number of moles of the gas
- 12. PV = nRT; a gas law that relates pressure, volume, temperature, and the amount for an ideal gas
- 14. Another common name for millimeters of mercury, named after Evangelista Torricelli the inventor of the barometer
- 15. States that when the pressure on a sample of a dry gas is held constant, the temperature in kelvins and the volume are directly related
- 16. An apparatus that measures atmospheric pressure by allowing it to support a column of liquid
- 17. Used when measuring gases, 0 degrees C
- 18. The SI unit of pressure, named for Blaise Pascal
- 20. Pressure is measured in force per unit of area, normal atmospheric pressure at seal level is 14.7...
- 21. The ability of a gas to mingle with or pass through another porous substance
- 23. The volume that a mole of gas occupies if it is at standard temperature and pressure
- 24. The total pressure, which equals the atmospheric pressure, is made up of the partial pressures of the gas and water vapor
- 25. States that under equivalent conditions, the volumes of reacting gases and their gaseous products are expressed in ratios of small whole numbers
- 26. When gases experience lower pressure, they quickly expand to fill the available space
- 27. The normal atmospheric pressure at sea level at 45 degrees latitude
Down
- 1. A gas whose behavior is perfectly predicted by the kinetic-molecular theory
- 2. Relates the units of pressure, volume, temperature, and quantity; R=PV/nT
- 3. States that the rate of effusion for a gas is inversely proportional to the square root of its molar mass
- 5. The average force exerted per unit of an area when molecules collide against a boundary
- 6. States the volume of a dry gas in inversely related to the pressure if the temperature is held constant
- 8. The pressure and the length of a column's unit
- 9. A gas law that combines Boyle's law, Charles's law, and Gay-Lussac's law, where temperature, pressure, and volume are constant; P1V1/T1 = P2V2/T2
- 10. States that the total pressure of a mixture of gases equals the sum of the partial pressures
- 11. States that pressure is directly proportional to temperature in kelvins for a fixed mass of gas held in a constant volume
- 13. When a gas enters a vacuum
- 19. The ability to flow and take the shape of their container
- 22. The process in which gas particles pass through a tiny opening into an evacuated chamber or space
