## Isothermal processAn ## Additional recommended knowledgeConsider an ideal gas, in which the temperature depends only on the internal energy, which is a function of the mean translational kinetic energy of the molecules, as given by a Boltzmann distribution; if the internal energy is constant, so is the temperature. Take the number of moles but this means, according to the ideal gas law, that so that where
Curves called
By the first law of thermodynamics, the isotherms of an ideal gas are also determined by the condition that where
In a minute process of this process, the minute work *d**W*=*F**d**x*=*P**S**d**x*=*P**d**V*
Therefore the entire work of the process from A to B is shown with the integration of the previous equation. Here, by the ideal gas equation, Therefore in the isothermal process, the following equation is formed.
Isothermal processes can occur in any kind of system, including highly structured machines, and even living cells. Various parts of the cycle of some heat engines are carried out isothermally and may be approximated by a Carnot cycle.
