Gas Laws

(Lecture id-1043)

TOPICS & OBJECTIVES

1015 - 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.
    1030 - Define pressure (P) and describe how a barometer and manometer are used to measure pressure.
    1040 - Convert between units of atm, torr, and mmHg.
    1050 - Define STP (standard temperature and pressure).
    1060 - State Boyles law and relate changes in volume to changes in pressure, if T and n do not change.
    1070 - Describe how J.A.C. Charles observations lead to the Kelvin temperature scale.
    1080 - Convert between measurements of Celcius and Kelvin.
    1100 - State Charles law and relate changes in temperature to changes in volume, if P and n do not change.
    1110 - State Gay-Lussacs law and relate changes in temperature to changes in pressure, if V and n do not change.
    1120 - State the combined gas law and use it to quantitatively solve before and after PVT problems.
    1140 - State Avogadros law and relate changes in moles to changes in volume, if P and T do not change.
 
1020 - Ideal Gas Law
    1010 - Derive the ideal gas law from Avogadros law and Gay-Lussacs law.
    1020 - 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.
    1110 - Know and understand the relationship between molar volume, molar mass, and gas density.
    1115 - Calculate the denisty of a gas not at STP with the ideal gas equation.
    1120 - Compare the relative density of two gases at any temperature from molecular weight.
 
1030 - Gas Mixtures
    1020 - Define a vapor, vapor pressure and partial pressure.
    1030 - Define a partial pressure and derive Daltons law from the ideal gas law.
    1040 - Determine the partial pressure of a gas over water from observed pressure and a vapor pressure table.
    1050 - Define and determine mole fraction of a component in a mixture.
    1060 - Use mole fraction of one component of a mixture to relate its partial pressure to the total pressure.
    1070 - Determine the moles of one component of a mixture from total moles, using partial and total pressure.
