| 5 MINUTES | INTRODUCTION -State Charles’ law. | Discussion. Questions and answers. | -Chalk board/white board. -A piece of chalk/ marker pen. | Longhorn Book III PP 9-14 |
| 30 MINUTES | BODY DEVELOPMENT 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 inter-conversion of the units. Students complete a table of temperature in the two units Derive equations from volume and temperature relationship. Exposition: – Teacher exposes a volume-temperature graph and extrapolates it to obtain the absolute temperature. The definition of absolute temperature is exposed. Worked examples. Supervised exercise. | Teacher demonstration:- To show expansion of air when heated and contraction when pressure is constant. Explain increase in volume when temperature is raised.
