Expert Answer
- P: Absolute pressure, in units of Pascals (Pa).
- V: Volume, in units of cubic meters (m3).
- T: Absolute temperature, in units of Kelvins (K).
- n: The number of moles of gas.
- N: The number of molecules of gas.
- NA: Avogadros number, the number of items in a mole of items, approximately equal to 6.022 x 1023.
- R: The gas constant, approximately equal to 8.314 J/mole.K.
- kB: Boltzmann constant, approximately equal to 1.38 x 10-23 J/K
: The average translational kinetic energy of the gas molecules, in units of Joules (J).- U: The internal energy of the contained gas, in units of Joules (J).
: a differential of heat added to the gas, in units of Joules (J).
: a differential of work done on the gas, in units of Joules (J).- Cv: The heat capacity for transformations at constant volume, in units of J/K
- cv: The specific heat for transformations at constant volume, in units of J/mole.K
- Cp: The heat capacity for transformations at constant pressure, in units of J/K
- cp: The specific heat for transformations at constant pressure, in units of J/mole.K
:The ratio of Cp to Cv, equal to the ratio of cp to cv
