Temperature versus volume relationship (Charles’ law). T vs V relationship. 20 slide PPT lesson on Charles’ law. It covers: temperature, KE, the Kelvin scale, absolute zero, how to convert between Kelvin and degrees Celsius (centigrade) and vice versa. It then moves on to the relationship between temperature and volume and calculating temperatures and volumes using Charles’ Law. Also covers all the key language. Well organised and succinct with clearly made key points and well chosen images. This lesson explains the material in an easy to understand way. Provides an excellent ready to use lesson on this topic, or it can easily be adapted if you wish. UK KS4 and USA grades 9 to 11 (ages 13 to 16). If you bought my “Charles’ law" lesson, please note that is very similar to this lesson, please do not buy both. Happy teaching!
