Online calculator, figures and tables showing dynamic (absolute) and kinematic viscosity of gasous and liquid ammonia at temperatures ranging from -73 to 425°C (-100 to 800°F) at pressure ranging from 1 to 1000 bara (14.5 - 14500 psia) - SI and Imperial Units. Ammonia - Properties at Gas-Liquid Equilibrium Conditions.
How can we use the laws of mechanics that describe the motions and interactions of individual atomic particles to predict macroscopic properties of the system such as pressure, volume, and temperature? In principle, each point-like atomic particle can be specified by its position and velocity (neglecting any internal structure).
The critical temperature of a gas provides insight into the strength of the intermolecular forces of attraction that its particles are subject to. For example, a gaseous substance with relatively weak intermolecular forces will be harder to liquefy than a gaseous substance featuring stronger intermolecular forces of attraction.
A second defining temperature of a real gas is the critical temperature, T C, the temperature at and above which the gas phase can not be condensed into the liquid phase, no matter how great the pressure becomes. In Figure \(\PageIndex{5}\) for isopentane, the isotherm for the critical temperature of 187ºC shows that the compound is not ...
The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant, random motion. The rapidly moving particles constantly collide with each other and with the walls of the container.
How well do real gases conform to the equation of state for an ideal gas? The answer is quite well over a large range of P, V and T, provided that the temperature is well above the critical temperature. We'll have to see shortly what is meant by the critical temperature; for the moment
