Rms speeds at 20 degrees celcius of atoms of helium

  1. Aug 17, 2004 #1
    1. Calculate the rms speeds at 20 degrees celcius of atoms of
    helium (4u)?

    2. The escapte speed from the surface of the earth is 11.2 km/s. Find at what temp. the following gas (O2) have this value as the rms speed?

    3. One mole of an ideal monatomic gas is heated from 0 degrees celcius to 100 degrees celcius. Find the chnage in internal energy and the heat absorbed, given that the process takes place under the follwoing condition:
    (a) constant volume
    (b) constant pressure
