How researchers discovered that a lethal gas, nitric oxide, was behind some of the most basic functions of the human body. It is manufactured in cells and involved in functions from blood pressure control to...
The 1991 Christmas Lecture 1991 in which Dave Nicholls tells how air is liquified and separated, then shows the effect on materials of freezing in liquid nitrogen. Demonstrates the burning of materials from...
Reconciles the physicist’s experience of gases on a large scale with the quantum mechanical description of the particles they comprise. Uses animations and studio models to look at the distribution of...
Shows the use of the Gilson differential respirometer in the measurement of exchange of gases between an organism and its environment.
A general introduction to the kinetic theory of gases, making extensive use of large-scale models of molecules.
Examines trends in the chemistry of the halogens and noble gases, and shows how molecules are able to absorb energy from light giving rise to infrared spectra.
Shows how the behaviour of liquid heium can be explained by the way atoms are counted in various energy levels available to them. Illustrates the way energy can be distributed among atoms by using snookers...
Part 1: Introduces the idea of three phases, and the transition between them, whilst concentrating on the liquid-gas phase. Also discussed are triple point, critical point, PVT equilibrium surface,...
Part 1 introduces the concept of an ideal gas, and gives a worked example using the two equations mentioned. Part 2 derives some more useful property relationships. Gives details as to what and when...
Shows gas flow at various pressures and speeds using initially a sodium molecular beam and then actual gas flow in a supersonic flow chamber. Bow and barrel shock waves are shown together with scattering...
