The Lascells Charles’ Law Set is a convenient tool for exploring the relationship between the volume (V) and temperature (T) of a gas. Both a graduated capillary and a thermometer are mounted on a board for easy suspension in a water bath. An oil or mercury bead can be added to the capillary tube (full instructions are provided). Using the apparatus, students can collect data to prove the directly proportional relationship between V and T, and extrapolate a value for Absolute Zero, to a very good approximation. Available individually (SED0200), or as a class set of 10, supplied in a Gratnells Tray (SED0202).
