Lesson Plan: Specific Latent Heat Physics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the formula 𝐸 = 𝑚𝐿 to calculate the amount of energy absorbed or released by a change in the state of a material.
Objectives
Students will be able to
- use to calculate the amount of energy needed to completely melt or boil a substance and the amount of energy released when a substance freezes or condenses,
- understand that a substance’s internal energy increases but its temperature doesn’t increase because it is undergoing a phase transition,
- identify changes of state in temperature–time graphs.
Prerequisites
Students should already be familiar with
- specific heat capacity,
- using in all permutations,
- using in all permutations,
- the three most common states of matter on Earth: solids, liquids, and gases,
- the names for the phase transitions between solids, liquids, and gases,
- the idea that the molecules in a material are held together by bonds.
Exclusions
Students will not cover
- states of matter other than solid, liquid, and gas,
- substances at ultralow temperatures.
