Gas Laws

(Lecture id-1030)

TOPICS & OBJECTIVES

1010 - Gas State
    1010 - Describe how gases differ qualitatively from other states by compressibility, energy (per volume), and density.
    1020 - Describe how measurements of volume (V), temperature (T), and moles (n) per volume quantify these properties.
 
1020 - Pressure
    1010 - Define pressure (P).
    1020 - Describe how a barometer and manometer are used to measure pressure.
    1030 - Convert between units of atm, torr, and mmHg.
    1040 - Define STP (standard temperature and pressure).
 
1030 - Simple Gas Laws
    1020 - Qualitatively relate changes in volume to changes in pressure, if T and n do not change.
    1030 - State Boyle's law and use it to quantitatively solve before and after PV problems.
    1032 - Describe how J.A.C. Charles observations lead to the Kelvin temperature scale.
    1035 - Convert between units of Celcius and Kelvin.
    1040 - Qualitatively relate changes in temperature to changes in volume, if P and n do not change.
    1050 - State Charles' law and use it to quantitatively solve before and after TV problems.
    1060 - Qualitatively relate changes in temperature to changes in pressure, if V and n do not change.
    1070 - State Gay-Lussac's law and use it to quantitatively solve before and after PT problems.
 
1040 - Combined Gas Law
    1010 - Derive the combined gas law from Boyle's law, Charles' law, and Gay-Lussac's law.
    1020 - State the combined gas law and use it to quantitatively solve before and after PVT problems.
 
1050 - Ideal Gas Theory
    1010 - Describe how atomic theory explains the observations of the simple gas laws.
    1020 - State Avogadro's law, use it to compare the moles of different volumes of gas, at constant T and P.
    1030 - Derive the ideal gas law from Avogadro's law and Gay-Lussac's law.
    1040 - State the ideal gas constant (R) and describe why it is unique from the constants in the simple gas laws.
    1050 - State the ideal gas law and given three of T, P, V and n, determine the fourth.
 
1060 - Gas Mixtures
    1010 - Describe the procedure for capturing gases over water.
    1020 - Define a vapor, vapor pressure and partial pressure.
    1030 - Derive Dalton's law of partial pressures from the ideal gas law.
    1040 - Determine the partial pressure of a gas over water from observed pressure and a vapor pressure table.
