General. Energy is a scalar quantity and the mechanical energy of a system is the sum of the potential energy (which is measured by the position of the parts of the system) and the kinetic energy (which is also called the energy of motion): [1][2] The potential energy, U, depends on the position of an object subjected to gravity or some other ...
C 6 H 6 (l) 124.5. 31.00. The standard Gibbs free energy of formation of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of that substance from its component elements, in their standard states (the most stable form of the element at 25 °C and 100 kPa). Its symbol is Δ fG ˚.
The Ministry of Energy and Mineral Resources of the Republic of Indonesia (Indonesian: Kementerian Energi dan Sumber Daya Mineral Republik Indonesia, abbr. Kementerian ESDM) is an Indonesian ministry responsible for providing assistance to the President and Vice President in performing government's affairs in the field of energy and mineral resources.

In 2017, Indonesia had 52,859 MW of installed electrical capacity, 36,892 MW of which were on the Java–Bali grid. [14] In 2022, Indonesia had an electrical capacity of 81.2 GW with a projected capacity of 85.1 GW for 2023. [15] In 2021, Indonesia's total energy supply (TES) comprised 30.3% coal, 28.9% oil, and 14.4% natural gas.
The internal energy of an ideal gas is proportional to its amount of substance (number of moles) and to its temperature. where is the isochoric (at constant volume) molar heat capacity of the gas; is constant for an ideal gas. The internal energy of any gas (ideal or not) may be written as a function of the three extensive properties ...

e. In thermodynamics, the Helmholtz free energy (or Helmholtz energy) is a thermodynamic potential that measures the useful work obtainable from a closed thermodynamic system at a constant temperature (isothermal). The change in the Helmholtz energy during a process is equal to the maximum amount of work that the system can perform in a ...
The laws of thermodynamics are a set of scientific laws which define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium. The laws also use various parameters for thermodynamic processes, such as thermodynamic work and heat, and establish relationships ...
