Introduction
The package provides information needed to set up and present a short practical demonstration in a lecture. This LDP (Lecture Demonstration Package) is centred on how is cooling of bi-material strips to generate curvature. The relationship between the curvature of a bi-material strip, the stiffness and thermal expansivities of the materials from which it is made, and the temperature change undergone is examined. The boiling temperature of nitrogen is then estimated by using this relationship and measuring the change in shape of a bi-material strip made from materials (steel and aluminium, aluminium and a polybicarbonate, steel and a polybicarbonate) of known thermal expansivities.
