Document Summary

Avogadro"s law: equal volumes of different gases, at the same temperature and pressure, contain equal number of molecules. If the number of molecules of a gas increase, the volume of the gas must also increase in a linear fashion: one mole of any gas at the same temperature and pressure will occupy the same volume. Equal amounts of different gases at the same temperature and pressure contain the same number of moles. At constant temperature and pressure, the volume of a gas is directly proportional to the number of moles. As such, they do not have any rotational energy, only translational. When the temperature increases, the kinetic energy increases. The kinetic energy of the gas molecules is ek = 0. 5mu2: u is the mean-squared speed and is found by taking the average of the squares of the speeds of the molecules.
