Lesson Plan: Boyle’s Law Physics

Start Practising

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.
