Thermodynamic Energy Equation

</dt>
The mathematical statement of the concept of conservation of energy embodied in the first law of thermodynamics. For reversible processes of a perfect gas, it may

be written in the form
pQ = ρcv (dT/dt) - (p/ρ) (dρ) (dt)

where pQ is the rate of energy addition per unit volume by heating (including the effects of radiation, molecular conduction, condensation water vapor, and the generation of heat by friction); T is the Kelvin temperature; cv is the specific heat at constant volume; p is pressure; and ρ is density. See energy equation. [[/a>|/a> ]]
