Gas laws
A Gas Uniformly fills any container. Mixes completely with any other gas Exerts pressure on its surroundings. A Gas It might help to define a gas based on the other phases as well. -Movie Clip- Kinetic Molecular Theory 1. Volume of individual particles is ? zero. 2. Collisions of particles with container walls cause pressure exerted by gas. 3. Particles exert no forces on each other. 4. Average kinetic energy ? Kelvin temperature of a gas. The Meaning of Temperature Kelvin temperature is an index of the random motions of gas particles (higher T means greater motion.) -Kinetic Energy Video- Pressure is equal to force/unit area SI units = Newton/meter2 = 1 Pascal (Pa) 1 standard atmosphere = 101,325 Pa 1 standard atmosphere = 1 atm = 760 mm Hg = 760 torr atm mmHg torr
