Helium (He) - Helium is the element whose atomic number is 2. It is denoted by the symbol He. To learn more about the physical & chemical properties of helium and its uses visit BYJU'S.
The theory of the degeneration phenomena of an ideal Bose-Einstein gas is modified so as to make it more in accordance with the thermal phenomena of liquid helium II. At the lowest temperatures the specific heat can be brought in agreement with the experimental data when the plausible assumption...

uniform pressure on the walls of the container. This is a unique property of gases and is independent of outside influences such as gravitational forces. When the gas molecules collide with the walls of the container or with each other they do so without any loss in total kinetic E. Fig....

ronment on the properties of amorphous carbon film [23] and observed the highest value of electrical conductivity of the film deposited in the helium gas environment. This motivated us to investigate the effect of helium gas environment on the electrical properties of carbon thin films. The...
In order to explain certain properties of thin helium films, Ziman has proposed an ideal gas model in which the bulk liquid is treated as a collection of independent, Bose–Einstein assemblies each a few hundred angstroms in extent. In this paper, an extensive numerical study is made of the...
