Isotherms of an ideal gas for different temperatures. The curved lines are rectangular hyperbolae of the form y = a/x. They represent the relationship between pressure (on the vertical axis) and volume (on the horizontal axis) for an ideal gas at different temperatures: lines that are farther away from the origin (that is, lines that are nearer to the top right-hand corner of the diagram ...
At one point, when the overlap becomes significant, a macroscopic number of particles condense into the ground state. In condensed matter physics , a Bose–Einstein condensate ( BEC ) is a state of matter that is typically formed when a gas of bosons at very low densities is cooled to temperatures very close to absolute zero , i.e., 0 K (− ...
By the equipartition theorem, internal energy per mole of gas equals c v T, where T is absolute temperature and the specific heat at constant volume is c v = (f)(R/2). R = 8.314 J/(K mol) is the universal gas constant, and "f" is the number of thermodynamic (quadratic) degrees of freedom, counting the number of ways in which energy can occur.
The above expression for vapor quality can be expressed as: = where is equal to either specific enthalpy, specific entropy, specific volume or specific internal energy, is the value of the specific property of saturated liquid state and is the value of the specific property of the substance in dome zone, which we can find both liquid and vapor .
A gas is a compressible fluid. Not only will a gas conform to the shape of its container but it will also expand to fill the container. In a gas, the molecules have enough kinetic energy so that the effect of intermolecular forces is small (or zero for an ideal gas), and the typical distance between neighboring molecules is much greater than ...
In a gas of particles of individual diameter 2r, the cross section σ, for collisions is related to the particle number density n, and mean free path between collisions λ. In a gas of finite-sized particles there are collisions among particles that depend on their cross-sectional size. The average distance that a particle travels between ...
A proton is a stable subatomic particle, symbol p, H +, or 1 H + with a positive electric charge of +1 e (elementary charge).Its mass is slightly less than the mass of a neutron and approximately 1836 times the mass of an electron (the proton-to-electron mass ratio).
Gas blending is the process of mixing gases for a specific purpose where the composition of the resulting mixture is defined, and therefore, controlled. A wide range of applications include scientific and industrial processes, food production and storage and breathing gases.
