Eneigy. The SI unit of energy is the joule which is the work done when the point of appHcation of a force of one newton is displaced a distance... 

Jeffryes, Alec, 628 Joliot, Frederic, 517 Joliot-Curie, Irfcne, 248 Joule The base SI unit of energy, equal to the kinetic energy of a two-kilogram mass moving at a speed of one meter per second, 135,635 Joule, James, 199... 

The symbol J here means joule, which is the SI unit of energy. 

The International Union of Pure and Applied Chemistry (IUPAC) recommends the use of the International System of Units (SI) in all scientific and technical publications [13]. Appendix A list the names and symbols adopted for the seven SI base units, together with several SI derived units, which have special names and are relevant in molecular energetics. Among the base units, the kelvin (symbol K) and the mole (mol), representing thermodynamic temperature and amount of substance, respectively, are of particular importance. Derived units include the SI unit of energy, the joule (J), and the SI unit of pressure, the pascal (Pa). 

Fine, but what are the units of energy Well, that depends. The SI unit of energy is the joule (J), but the calorie (cal) and liter-atmosphere (L atm) are also used. Here s how the joule, the calorie, and the liter-atmosphere are related ... 

Joule obtained a much improved estimate of the Joule s equivalent of heat (Jjq = 4.15 J cal-1, within 1% of the modem value) and demonstrated its quantitative consistency for all these effects. Thus, Joule s name is rightly attached to the SI unit of energy, and he deserves to be considered the scientist most responsible for quantitative establishment of the first law of thermodynamics. 

SI units have been used throughout the book whenever possible. There are no feet, microns, miles, or tons. Molecular dimensions are given uniformly in nanometers rather than in angstrom units (A lA = 0.1 nm). Likewise the calorie and kilocalorie have been replaced by the SI unit of energy, the joule (J 1 calorie = 4.184 J). 

JOTT.F, (J) A unit of energy The work done Iry newton acting through a distance of 1 meter. (The SI unit of energy. One joule equals 1 watt-second equals IQ7 ergs, equals 107 dyne-centimelers.)... 

In this book we use kilocalories in place of the presently recommended (SI) joules for units of energy. As of the date of writing, it is not clear just how general the use of the joule will become among chemists. To convert calories to joules (or kcal to kJ), multiply by 4.184. 

The relationship between the volt and the SI units of energy (joule, J) and electric charge (coulomb, C) is given by the equation... 

The SI unit of energy is the joule (J), exactly the same unit as work. As an example, assume you have a 1 kg mass that you want to accelerate at 1 m/s2 over a distance of 1 m. The amount of energy you would use is ... 

Scientists must talk to one another in common quantities, units, and symbols. The International Union of Pure and Applied Chemistry (IUPAC) has drawn up tables of chemspeak (Mills et. al., 1993). The Systeme International (SI) unit of energy is the joule (J) and that of power is the watt (IV). In terms of SI base units the former is N m and the latter, J s 1. Older textbooks and scientific papers use the calorie (= 4.184 J) but today s scientists must use the multiplier to be correct when quoting earlier work using this antiquated unit. 

James Prescott Joule determined the equivalence of heat energy to mechanical work in the 1840s by carefully measuring the heat produced by friction. Joule attacked the caloric theory and played a major role in the acceptance of kinetic molecular theory. The SI unit of energy is named after him. 

A fundamental characteristic of the SI system is the fact that each defined quantity has only one unit. Thus, the fundamental SI unit of energy is the joule and the fundamental SI unit of power is the watt. While a joule is defined as a newton meter, it refers to a unit force moving through a unit distance. The... 

Although the SI unit of energy is the joule (J), organic chemists overwhelmingly report energy values In calories (cal). 

More complicated combinations are possible. For example, to convert from liter-atmospheres to joules (the SI unit of energy), two separate unit conversions are used ...
