Lesson Plan: Gay-Lussac’s Law Physics • Second Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the formula 𝑃/𝑇 = constant (Gay-Lussac’s Law) to calculate the pressure or temperature of a gas that is heated or cooled at a constant volume.
Objectives
Students will be able to
- know that, for an ideal gas at constant volume, the pressure, , of the gas is proportional to the temperature, ,
- use , where is a constant, to determine the pressure or temperature of a gas before or after a thermodynamic process that keeps the volume constant.
Prerequisites
Students should already be familiar with
- pressure,
- volume,
- density,
- temperature,
- states of matter,
- the idea that substances are made up of particles,
- the Kelvin temperature scale.
Exclusions
Students will not cover
- Boyle’s Law,
- Charles’ Law,
- the ideal gas law,
- the kinetic theory of gases,
- internal energy,
- entropy,
- phase changes.
