Using his extensive measurements of the properties of gases, [6] [7] Mendeleev also calculated it with high precision, within 0.3% of its modern value. [ 8 ] The gas constant occurs in the ideal gas law: P V = n R T = m R s p e c i f i c T {\displaystyle PV=nRT=mR_{\rm {specific}}T} where P is the absolute pressure , V is the volume of gas, n ...
Here because is a multivalued function, the integral must be divided into 3 parts corresponding to the 3 real roots of the vdW equation in the form, (,) (this can be visualized most easily by imagining Fig. 1 rotated ); the result is a special case of material equilibrium. [62]
The table below essentially simplifies the ideal gas equation for a particular process, making the equation easier to solve using numerical methods. A thermodynamic process is defined as a system that moves from state 1 to state 2, where the state number is denoted by a subscript.
Boltzmann constant: The Boltzmann constant, k, is one of seven fixed constants defining the International System of Units, the SI, with k = 1.380 649 x 10 −23 J K −1. The Boltzmann constant is a proportionality constant between the quantities temperature (with unit kelvin) and energy (with unit joule). [3]
In theoretical chemistry, Marcus theory is a theory originally developed by Rudolph A. Marcus, starting in 1956, to explain the rates of electron transfer reactions – the rate at which an electron can move or jump from one chemical species (called the electron donor) to another (called the electron acceptor).

[citation needed] The Schwarzschild radius would be 2 × 6.6738 × 10 −11 m 3 ⋅kg −1 ⋅s −2 × 6.3715 × 10 14 kg / (299 792 458 m⋅s −1) 2 = 9.46 × 10 −13 m = 9.46 × 10 −4 nm. Its average density at that size would be so high that no known mechanism could form such extremely compact objects.
For example, the logarithm of 1000 to base 10 is 3, because 1000 is 10 to the 3 rd power: 1000 = 10 3 = 10 × 10 × 10. More generally, if x = b y, then y is the logarithm of x to base b, written log b x, so log 10 1000 = 3. As a single-variable function, the logarithm to base b is the inverse of exponentiation with base b.
Notice here that this is a time-class. It is the set of pairs of machines and inputs to those machines (M,x) so that the machine M accepts within f(|x|) steps. Here, M is a deterministic Turing machine, and x is its input (the initial contents of its tape). [M] denotes an input that encodes the Turing machine M. Let m be the size of the tuple ...
