The gas constant R is defined as the Avogadro constant N A multiplied by the Boltzmann constant k (or k B): = = 6.022 140 76 × 10 23 mol −1 × 1.380 649 × 10 −23 J⋅K −1 = 8.314 462 618 153 24 J⋅K −1 ⋅mol −1. Since the 2019 revision of the SI, both N A and k are defined with exact numerical values when expressed in SI units. [2]
Repeating unit of melon, according to T. Komatsu (2001). [1] In chemistry, melon is a compound of carbon, nitrogen, and hydrogen of still somewhat uncertain composition, consisting mostly of heptazine units linked and closed by amine groups and bridges (–NH–, =NH, –NH 2, etc.). [2] It is a pale yellow solid, insoluble in most solvents. [1]
In physics, a Tonks–Girardeau gas is a Bose gas in which the repulsive interactions between bosonic particles confined to one dimension dominate the system's physics. It is named after physicists Lewi Tonks, who developed a classical model in 1936, and Marvin D. Girardeau who generalized it to the quantum regime. [1]

According to the American Petroleum Institute (API), a standard barrel of oil is the amount of oil that would occupy a volume of exactly 1 barrel (158.99 L) at reference temperature and pressure conditions of 60 °F (15.6 °C) and 14.696 psi (1,013.25 hPa) (or 1 atm). This standard barrel of oil will occupy a different volume at different ...
The General Electric LM6000 is a turboshaft aeroderivative gas turbine engine. The LM6000 is derived from the CF6-80C2 aircraft turbofan.It has additions and modifications designed to make it more suitable for marine propulsion, industrial power generation, and marine power generation use.
