Lesson Plan: Charles’ 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 𝑉/𝑇 = constant (Charles’s 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
- Boyle’s law
- Gay-Lussac’s law
- The ideal gas law
- The kinetic theory of gases
