Lesson Plan: Charles’ Law Physics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the formula π/π = constant (Charlesβs law) to calculate the volume or temperature of a gas that is heated or cooled at a constant pressure.
Objectives
Students will be able to
- use the formula to find the volume or temperature of a gas before or after a thermodynamic process in which the gas is kept at a constant pressure,
- describe in words what the physical meaning of is,
- use graphical methods to describe what the physical meaning of is,
- interpret graphs of .
Prerequisites
Students should already be familiar with
- pressure,
- density,
- temperature,
- volume,
- states of matter,
- the Kelvin temperature scale,
- how to convert between the Kelvin temperature scale and the Celsius and Fahrenheit temperature scales.
Exclusions
Students will not cover
- Boyleβs law
- Gay-Lussacβs law
- The ideal gas law
- The kinetic theory of gases
