Thermodynamics

Work Done by a Gas
Gives the mechanical work done by an expanding or compressing gas.
First Law of Thermodynamics
States conservation of energy where heat added equals internal energy change plus work done by the gas.
Work Done in a Cyclic Process
Gives the net work done by a gas over a closed cycle as the enclosed area on a PV diagram.
Internal Energy Change of an Ideal Gas
Gives the change in internal energy for an ideal gas, which depends solely on temperature change.
Work Done in an Isobaric Process
Gives the work done by an ideal gas during expansion or compression at constant pressure.
Heat Transferred in an Isobaric Process
Gives the heat absorbed or released by an ideal gas at constant pressure.
Work Done in an Isothermal Process
Gives the work done by an ideal gas during a reversible isothermal expansion or compression.
Adiabatic Process Equations
Relates pressure, volume, and temperature of an ideal gas along a reversible adiabatic path.
Work Done in an Adiabatic Process
Gives the work done by an ideal gas undergoing a reversible adiabatic process.
Bulk Modulus of an Ideal Gas
Gives the isothermal and adiabatic bulk moduli of an ideal gas.
Efficiency of a Carnot Engine
Gives the maximum theoretical efficiency of a heat engine operating between two temperatures.
Coefficient of Performance of a Refrigerator
Gives the coefficient of performance of an ideal Carnot refrigerator.
