Chemistry Ch.4 Crossword

9. a hypothetical gas composed of molecules which follows specific rules; one such rule is that gas molecules do not attract or repel each other
11. combines the three gas laws: Boyle’s Law, Charles’ Law, and Gay-Lussac’s Law
12. states that the pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant
13. states that for a given mass of a gas at constant temperature, the volume of the gas varies inversely with pressure
14. states that the rate of effusion of a gas is inversely proportional to the square root of the gas’s molar mass

1. states that at a constant volume and temperature, the total pressure exerted by a mixture of gasses is equal to the sum of the partial pressures of the component gass
2. the contribution each gas in a mixture makes to the total pressure
3. a measure of how much the volume of matter decreases under pressure
4. process that involves the movement of molecules in a gas; caused by gas escaping through a tiny hole in its container
5. has the value 8.31 (L*kPa)/(K*mol)
6. includes all four variables - P, V, T, and n
7. a gas that does not behave according to the assumptions of the kinetic-molecular theory
8. the tendency of molecules to move toward areas of lower concentration until the concentration is uniform throughout
10. states that the volume of a fixed mass of gas is directly proportional to its kelvin temperature if the pressure is kept constant
