the temperature-pressure relation
61Relations between heat capacities — The laws of thermodynamics imply the following relations between the heat capacity at constant volume, C {V}, and the heat capacity at constant pressure, C {P}::C {P} C {V}= V Tfrac{alpha^{2{eta {T,:frac{C {P{C {V=frac{eta {T{eta {S,Here alpha …
62Hydraulic brake — The hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing ethylene glycol, to transfer pressure from the controlling unit, which is usually near the operator of the vehicle, to the actual brake… …
63Atmospheric liquid water content — The liquid water content (LWC) of the atmosphere is the measure of the mass of the water in a cloud, typically in g/m3 or g/kg. (Bohren, 1998). This variable is important in figuring out which types of clouds are likely to form and is strongly… …
64Klincewicz method — The Klincewicz method [Klincewicz K. M., Reid R. C., Estimation of Critical Properties with Group Contribution Methods , AIChE Journal, 30(1), 137 142, 1984] is a predictive method based both on group contributions and on a correlation with some… …
65Laws of thermodynamics — The laws of thermodynamics, in principle, describe the specifics for the transport of heat and work in thermodynamic processes. Since their conception, however, these laws have become some of the most important in all of physics and other… …
66Causes of landslides — The causes of landslides are usually related to instabilities in slopes. It is usually possible to identify one or more landslide causes and one landslide trigger. The difference between these two concepts is subtle but important. The landslide… …
67Schumann resonances — The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth s electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, excited by lightning discharges in the …
68Acoustic impedance — The acoustic impedance Z (or sound impedance) is a frequency f dependent parameter and is very useful, for example, for describing the behaviour of musical wind instruments. Mathematically, it is the sound pressure p divided by the particle… …
69Level of measurement — The levels of measurement , or scales of measure are expressions that typically refer to the theory of scale types developed by the psychologist Stanley Smith Stevens. Stevens proposed his theory in a 1946 Science article titled On the theory of… …
70Lorentz–Lorenz equation — The Lorentz–Lorenz equation, also known as the Clausius–Mossotti relation and Maxwell s formula, relates the refractive index of a dilute gas to its temperature, pressure, and molar refractivity. The index of refraction n is given by: n approx… …
