Document Summary

Topics studied: relationship between pressure, volume and temperature, gas laws, kinetic molecular theory, chemistry and composition of the atmosphere. Energy storage: translational energy: energy from the motion of the molecule through space, vibrational energy, rotational energy, electronic energy. Temperature of a gas: measure of the average translational kinetic energy of gas molecule. Adding heat to a system will make the molecules move faster. Air pressure is in result of gravity pulling molecules down. 1atm = 760 mm hg = 760 torr. Placing a glass tube upside down of tube, with closed top. Mercury will fill up tube and create a vacuum at the top. Space between end of vacuum and dish is 760 mm of mercury. Volume and pressure are inversely proportional: (at a constant n, t) Volume and temperature and directly proportional: (at a constant n, p) Volume and moles are directly proportional: (at a constant t, p) Boyle"s law is imperfect, not always a perfect constant.
