Describe how the kinetic-molecular theory is used to explain how gases behave at
different temperatures. (Exploration 1)
Analyze data that shows how gas particle mass affects that gas’s behavior.
(Exploration 2) Based on the mass of the object, the gas particle can move quickly in
higher temperature or slower depending on the mass components.
(Explorations 1 and 2) With increasing
energy some of the particles will be found to be slower
Description of Activity
The kinetic-molecular theory states that a collection of gas molecules’ average kinetic energy has
a specific value at any given temperature. In this activity, you will study how temperature and
gas particle mass affect the frequency distribution of gas particle speeds. You will examine and
analyze speed frequency distribution graphs. This distribution is called the Maxwell-Boltzmann
What is kinetic energy? It is energy in motion
What is thermal energy? Movement of atoms and molecules
What happens to a gas’s thermal energy as that gas’s temperature increases?
particles decreases in speed
What happens to the average speeds of the particles in a gas when that gas’s temperature
