 Molar Mass of a Fictional Gas Using Temperature and Average Velocity in Gas Simulation Behavior

OBJECTIVES
• Calculate a hypothetical gas’s molar mass in a simulation.
• Recognize how kinetic energy and temperature are related.
INTRODUCTION
At normal temperatures, matter molecules can be thought of as moving rapidly and randomly indefinitely. The Boltzmann distribution can be used to determine the typical translational kinetic energy for these molecules. We can get the molecular mass by computing the velocity and temperature of these molecules at various temperatures.
The following ratio can be used to connect average velocities to temperature using the Boltzmann distribution of energies:
A single particle’s k value is 1.38 x 10-23 J/K T in Kelvin m of kg v in m/s.
By multiplying both sides by 2, we can get rid of the 1/2 element, giving us:

Simulation
Qualitative data, first
1. When a sealed system heats up, what do you anticipate will happen to the pressure of a gas?
cools off? What examples from your daily life do you use to back up your claims?
B. CONFIGURATION OF THE EXPERIMENT
Select “Constant Volume” in step 1.
2. Select “Species Information” under “Measurement Tools.”
