GL - Ideal Gas Law (Lesson)
Ideal Gas Laws
Introduction
An ideal gas is defined as one where all collisions between atoms or molecules are perfectly elastic and where there are no intermolecular attractive forces. You can visualize an ideal gas as a collection of spheres that collide but otherwise do not interact with each other. An ideal gas can be characterized using three variables: pressure (P), volume (V), and temperature (T). The relationship between them may be inferred from kinetic theory and is called the Ideal Gas Law and is represented by the equation below.
Ideal Gas Law
This segment dives further into the ideal gas law. It includes the students and teacher discussing the models the student made in segment D to demonstrate the relationship between pressure and volume in gases. The teacher gives the students an engineering and design challenge: create a safe model of an airbag using what they have learned about the behavior of gases.

Ideal Gas Law Practice
Air Bag Experiment
Students discuss the calculations and procedures they need for the model air bag experiment and begin making their models and recording their findings.
Students review and discuss the results from their model airbag experiment. Our host speaks with Lea Merriwether, water quality technician at Georgia Aquarium, to discuss how gas levels affect water quality.
