Gases & Kinetic Theory
Odyssey includes a series of 20 experiments on gases and kinetic theory:
Experiment demonstrating the effect of temperature on gases
The Density of Gases
Shows how gases occupy space relating to temperature and volume.
The Motion of the Molecules in a Gas
Demonstrates the movement of molecules in a gas with attention to molecule-molecule collisions.
The Forces between Gas Molecules
Illustrates (lack of) force between gas molecules.
The Temperature of a Gas
Investigates the temperature of gases and its proportionality to kinetic energy.
The Pressure of a Gas
Describes the relationship between pressure and it affect on particles in a gas.
The Volume of a Gas
Shows how gases behave with changes in volume of their environment.
The Ability of Gases to Mix
Illustrates the mixing of gases by simulating two gases exposed to each other in a container.
Introduces Boyles Law demonstrating the proportionality between pressure and volume.
The Pressure-Temperature Relationship
Investigates the proportionality between pressure and temperature.
Demonstrates Avogadro's Law showing the volume of a gas is proportional to the number of molecules in that gas.
The Universality of the Ideal Gas Law
Illustrates the similarity of gases thermodynamically even if many gases have different characteristics.
Shows how chemists use mole fractions very commonly in order to describe the composition of mixtures and particularly mixtures of gases.
The Molecular Speeds in a Gas
Demonstrates the distribution of speed of molecules within gases via an interactive experiment.
The Maxwell-Boltzmann Distribution of Speeds
Introduces the Maxwell-Boltzmann Distribution. Temperature and other parameters can be altered and the effect on the plotted distribution studied.
Speed Distribution and Temperature
Investigates the relationship between speed distribution of molecules and the temperature of the gas.
Speed Distribution and Molar Mass
Illustrates the mass dependence of the distribution of speeds.
The Speed Distribution for Gas Mixtures
Using and experiment this section describes the distribution of speeds for a mixture of gases.
Introduces the concept of effusion with an interactive experiment.
Demonstrates diffusion in relation to the mean free path of a molecule.
Gases at High Pressure
Shows how pressure effects the behavior of gases with an interactive experiment.
