Exploration 2: the Effect of Mass on Gas Behavior
Procedure
1. Set the temperature at 500 K. Maintain this temperature throughout this Exploration.
2. Select Hydrogen gas from the list box. Record the most probable particle speed and the average particle speed in Table 2. Gas, Most probable Particle Speed (ms), Average Particle Speed (ms), Mass of a Single Atom or Molecule (amu)
3. Calculate the mass of a gas particle from step 2 in amu. Refer for the periodic table for the masses of individual atoms. Be aware that a hydrogen gas particle contains two hydrogen atoms, and an oxygen gas particle contains two oxygen atoms. Record your result in Table 2.
4. Repeat steps 2 and 3 for Oxygen, Caron dioxide, and Xenon.
