Across
- 1. the total pressure in a gas mixture is equal to the sum of partial pressures of the individual gases
- 6. the random movement of gas molecules from an area of higher concentration to an area of lower concentration
- 7. the pressure of an individual gas when in a mixture of gases
- 9. the measure of the average kinetic energy of the particles in a sample of matter
- 10. the minimum amount of energy that must be applied to a system to initiate a chemical change
- 15. the change in heat of the products from the reactants
- 17. The ability of a substance to combine with or change into one or more other substances
- 18. diffusion through a tiny opening
- 19. the amount of heat/energy to raise 1 gram of a substance by 1 degree celecius
- 20. the rate of effusion for a gas is inversely proportional to the square root of it's molar mass
Down
- 2. The pressure exerted on the surface of the earth by the weight of the gases in the earth's atmosphere
- 3. A characteristic that can be observed or measured without changing the sample's composition
- 4. biological catalysts that speeds up the rate of reaction in the body
- 5. increases as temperature increases
- 8. the study of how heat is converted to and from other forms of energy and how it affected matter
- 11. the volume of a gas is inversely proportional to the pressure if temperature is held constant
- 12. the total amount of energy; movement
- 13. a substance that speeds up a chemical reaction without itself undergoing any chemical change
- 14. standard temperature and pressure
- 16. the pressure of a given mass of gas is directly proportional with the Kelvin temperature when volume is held constant
