Title: On the Air
Url: http://www.vega.org.uk/video/programme/75
Publisher: Vega Science Trust
Description: This video lecture includes discussion of 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 lecture includes a demonstration of superconductivity with the effect of flux pinning. The lecture is 59 minutes in length.
