Page 3: Molecular Behavior and Pressure Relationships

This page examines the molecular-level explanations for pressure changes in gases and predicts behavior in flexible containers.

Definition: Gas pressure results from molecules colliding with container walls.

Example: Adding more molecules increases collision frequency, while heating increases both collision frequency and force.

Highlight: In flexible containers, volume adjusts to equalize internal and external pressures.

Page 4: Flexible Container Experiments

This page presents experiments examining gas behavior in flexible containers under various conditions, including changes in volume, temperature, and external pressure.

Definition: External pressure refers to the force exerted on a container from the outside environment.

Vocabulary: Atmospheric pressure (atm) - The standard unit of pressure measurement.

Page 1: Introduction to Gas Variables

This page introduces the fundamental concepts of gas behavior through a practical example of helium-filled balloons. The text explores how different conditions affect gas behavior in various container types.

Example: A balloon bouquet scenario is used to demonstrate how helium gas behaves in different temperatures and container materials.

Highlight: The four main variables discussed are pressure (P), volume (V), temperature (T), and moles (n) of gas.

Definition: Model 1 presents two experiments examining gases in nonflexible containers, showing how adding gas and heating affect internal pressure.
