Gases

1. the scientist summarized the results of his experiments by stating that at constant temperature and pressure the volume of gaseous reactants and products can be expressed as ratios of small whole numbers
5. a device used to measure atmospheric pressure
9. pressure of each gas in a mixture
10. states that equal volume of gases at the same temperature and pressure contain equal numbers of molecules
13. the lowest possible achievable temperature is assigned the value of zero on the kelvin temperature scale
15. states that the rates of effusion of gases at the same temperature and pressure are inversely proportional to the square roots of their molar masses
16. expresses the relationship between pressure, volume, and temperature of a fixed amount of gas
17. states that the total pressure of a gas mixture is the sum of the partial pressures of the component gases
18. in the equation representing the ideal gas law the constant R

2. defined as being exactly equivalent to 760 mm Hg
3. is defined as the force per unit area on a surface
4. it had been found to be 22.414 10 L
6. states that the volume of a fixed mass of gas varies inversely with the pressure at constant temperature
7. common unit of pressure symbolized mm Hg
8. is the mathematical relationship among pressure, volume, temperature, and the number of moles of a gas
11. states that the volume of a fixed mass of gas at constant pressure varies directly with the temperature in kelvins
12. is the force that will increase the speed of a one kilogram mass by one meter per second each second that the force is applied.
14. defined as the pressure exerted by a force of one newton acting on an area of one square meter
15. the pressure of a fix mass of gas at constant volume varies directly with the temperature in kelvins
