Across
  1. 2. law that states the pressure of a gas is directly proportional to the Kelvin temperature if the volume is constant
  2. 3. law that states the relationship between pressure, temperature, and volume of an enclosed gas
  3. 4. unit of pressure (atm)
  4. 7. Law that states the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant
  5. 10. the pressure exerted by atoms and molecules in the atmosphere surrounding earth, resulting in collisions of these particles with objects
  6. 12. R in the ideal gas equation
  7. 13. the tendency of molecules to move toward areas of lower concentration unitl the concentration is uniform throughout
  8. 14. the energy an object has because of its motion
  9. 15. results from the force exerted by a gas per unit surface area of an object, due to collisions of gas particles with objects
  10. 17. law that states the rate of effusion is inversely proportional to the square root of its molar mass
Down
  1. 1. the contribution each gas in a mixture of gases makes to the total pressure
  2. 3. a measure of how much the volume of matter decreases with pressure
  3. 5. Law that states for a given mass at a constant temperature, the volume of the gas varies inversly with pressure
  4. 6. law that states at a constant volume and temperature, the total pressure exerted by a mixture is equal to the sum of the partial pressures of the component gasses
  5. 8. the relationship described in PV=nRT
  6. 9. an instrument used to measure atmospheric pressure
  7. 11. the process that occurs that when a gas escapes through a tiny hole in its container
