Michael Garrett discusses the physical properties of gases and demonstrates how air is liquefied. Liquefied gases are a key resource for survival with an amazing range of applications and there are now few industries which are not in some way dependent on this major raw material. Life-saving operations in hospitals, the purification of polluted rivers and lakes, and superconductivity are but a few fields which require liquefied gas supplies. The presentation also includes a demonstration of superconductivity and flux pinning.
