Residual property (physics) ... a residual property is defined as the difference between a ... reduces to an ideal gas in the limit of infinite volume, ...
The molar volume of a mixture can be found from the sum of the excess volumes of the components of a mixture: = (+ ¯). This formula holds because there is no change in volume upon mixing for an ideal mixture. The molar entropy, in contrast, is given by
For example, to evaluate enthalpy change between two points h(v 1,T 1) and h(v 2,T 2) we first compute the enthalpy departure function between volume v 1 and infinite volume at T = T 1, then add to that the ideal gas enthalpy change due to the temperature change from T 1 to T 2, then subtract the departure function value between v 2 and ...
Functional residual capacity (FRC) is the volume of air present in the lungs at the end of passive expiration. [1] At FRC, the opposing elastic recoil forces of the lungs and chest wall are in equilibrium and there is no exertion by the diaphragm or other respiratory muscles.
In thermodynamics, the Gibbs free energy (or Gibbs energy as the recommended name; symbol ) is a thermodynamic potential that can be used to calculate the maximum amount of work, other than pressure–volume work, that may be performed by a thermodynamically closed system at constant temperature and pressure.
Specific volume is the volume occupied by a unit of mass of a material. [1] In many cases, the specific volume is a useful quantity to determine because, as an intensive property, it can be used to determine the complete state of a system in conjunction with another independent intensive variable .
The volume of such a mixture is slightly less than the sum of the volumes of the components. Thus, by the above definition, the term "40% alcohol by volume" refers to a mixture of 40 volume units of ethanol with enough water to make a final volume of 100 units, rather than a mixture of 40 units of ethanol with 60 units of water.
In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure (C P) to heat capacity at constant volume (C V).
