Teacher demonstration: To show expansion of air when heated and contraction when pressure is constant. Explain increase in volume when temperature is raised. Q/A: – relation between volume and temperature, leading to Charles’ law. Teacher explains interconversion of the units. Students complete a table of temperature in the two units Derive equations from volume and temperature relationship.
Exposition: – Teacher exposes a volumetemperature graph and extrapolates it to obtain the absolute temperature. The definition of absolute temperature is exposed. Worked examples. Supervised exercise.
