The First Law of Thermodynamics
Constant Volume and Pressure in Thermodynamics
Description
Thermodynamic processes can happen at constant volume or at constant pressure. An isochoric process is a constant-volume process. In this case, the volume does not change, so the work done by the system is zero. The first law of thermodynamics still applies, so any heat added or removed changes the internal energy of the sys...

Un proceso termodinámico que ocurre a volumen constante se denomina proceso isocórico.
Considere la evaporación que ocurre dentro de un ecosistema sellado. Dado que el vapor de agua no escapa del recipiente, el volumen permanece constante y el proceso es isocórico.
A volumen constante, el sistema no realiza ningún trabajo. Ahora, a...
