# Lesson Plan: Boyle’s Law Physics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the formula 𝑃𝑉 = constant (Boyle’s law) to calculate the pressure or volume of a gas that is allowed to expand or contract at a constant temperature.

#### Objectives

Students will be able to

- know that for an ideal gas at constant temperature, the pressure, , of the gas is inversely proportional to the volume, ,
- use , where is a constant, to determine the pressure or volume of a gas before or after a thermodynamic process that keeps the temperature constant,
- understand diagrams that represent the particles of a gas and how Boyle’s Law can be shown using these diagrams.

#### Prerequisites

Students should already be familiar with

- pressure,
- volume,
- density,
- temperature,
- states of matter,
- the idea that substances are made up of particles.

#### Exclusions

Students will not cover

- Gay-Lussac’s law,
- Charles’ law,
- the ideal gas law,
- the kinetic theory of gases,
- internal energy,
- entropy,
- phase changes.
