    Helium Gas: Pressure, root-mean-square velocity, and more

    Oh, so you're saying the mass in the equation is of one Helium atom, not the total mass in the container. OH; I used the mass in the container, and seeing that there was one mole of gas, the mass would have been 4g. But I see now. Thank you!

    Helium Gas: Pressure, root-mean-square velocity, and more

    Homework Statement A rigid, thermally insulated container with a volume of 22.4 liters is filled with one mole of helium gas (4 grams per mole( at a temperature of 0 Cesius (273K). The container is sitting in a room, surrounded by air at standard temperature and pressure (STP:1atm, 0...

    Inter-atomic force in a Hydrogen molecule - finding spring stiffness

    Inter-atomic force in a Hydrogen molecule -- finding "spring" stiffness Homework Statement At about 2000 K the heat capacity (at constant volume =) increases to (7/2)k per molecule due to contributions from vibrational energy states. Use these observations to estimate the stiffness of the...
