Ideal gas Law question due 03/04/12 @10:00 pm

Describe the contributions of Guy-Lussac, Charles, Avogadro, and Boyle to the ideal gas law. Also, explain the significance of Graham's Law.

22 comments:

  1. Gay Lussac contributed by showing the ratio of the volumes of gases involved in a chemical reaction.
    Charles contributed by showing the relationship between temperature and volume of gas, which was that the volume of gas was directly proportional to its temperature.
    Avagadro argued that Gay-Lussac's law of combining volumes could be explained by assuming that equal volumes of different gases collected under similar conditions contain the same number of particles.
    Boyle contributed by showing that the product of the pressure times the volume for any measurement was equal to the product of the pressure times the volume for any other measurement.
    The significance of Graham's Law was that he found that the rate of effusion of a gas is inversely proportional to the square root of the mass of its particles.

  2. Gay-Lusac's law states that the pressure exerted on a container's sides by an ideal gas is proportional to the absolute temperature.

    Charles Law says that for an ideal gas at constant pressure, the volume is directly proportional to the absolute temperature in kelvin.

    Boyle's law shows that, at constant temperature the product of an ideal gas's pressure and volume is always constant.

    Avogadro's law says that states that the volume occupied by an ideal gas is proportional to the number of moles.

    Graham's law says that the rate at which gas molecules diffuse is inversely proportional to the square root of its density.

  3. Boyle- Product of pressure and volume are always equal provided that the temperature is constant P1V1=P2V2
    Charles- Temperature (K) is directly proportional to volume provided that the ideal gas remains at constant pressure V1/T1=V2/T2
    Avogadro- equal volumes of different gasses contain the same number of particles, meaning that the volume of an ideal gas is proportional to the number of moles.n1/V1=n2/V2
    Gay-Lussac- Pressure is directly proportional to the temperature in kelvin of an ideal gas. P1/T1=P2/T2

    Combined, these laws help deduce the ideal gas law PV=nRT

    Graham- The rate at which gas molecules diffuse is inversely proportional to the square root of its density. Combined with Avogadro's law (i.e. since equal volumes have equal number of molecules) this is the same as being inversely proportional to the root of the molecular weight.

  9. The Gay-Lussac law states that the values for temperature and pressure of a gas are directly related. As the temperature of a gas increases, so will the average speed and kinetic energy of the particles. This relationship is expressed in the following equation, P/T= k where P is the pressure of the particles on the container, T is the temperature in Kelvins, and k is a constant. At constant volume, this results in more collisions and thereby greater pressure the container.

    Avogadro’s law states that the volume of a gas is directly related to the number of moles of atoms contained in the gas. The equation for Avogadro's law is V/n= k where V is the volume of the container, n is the amount of gas as measured by the moles of atoms, and k is a constant.

    Charles’ law states that the values for temperature and volume of a gas are directly related. The equation for Charles' law is V/T=k where V is the volume of the container, T is the temperature of the system in Kelvin, and k is the constant. For changes in volume and temperature, k remains the same.

    Boyle’s law states that for the pressure and volume of a gas, when one value increases the other decreases, as long as temperature and number of moles remain constant. Boyle's law is summarized by the equation PV=k where P is the pressure of the molecules on the container, V is the volume of the container, and k is a constant. The value of k always stays the same so that P and V vary appropriately. For example, if pressure increases, k must remains constant and thus volume will decrease.

    Graham's law states that a gas's rate of effusion is inversely proportional to the square root of the mass of its particles and is significant because it enables scientists to determine the rate at which gases diffuse.

  10. Gay-Lussac's Law- for a given amount of gas held at constant volume, the pressure is proportional to the absolute temperature.
    Avogadro's Law-two given samples of an ideal gas, of the same volume and at the same temperature and pressure, contain the same number of molecules.
    Charle's Law-At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature on the absolute temperature scale
    Boyle's Law-For a fixed amount of an ideal gas kept at a fixed temperature, P [pressure] and V [volume] are inversely proportional (while one doubles, the other halves).
    Graham's Law-the rate of effusion of a gas is inversely proportional to the square root of the mass of its particles.
