Thermodynamics formulas
Important thermodynamics formulas are illustrated below:
First Law of Thermodynamics (Energy Conservation)
ΔU = Q − W
Where:
- ΔU is the change in internal energy,
- Q is the heat added to the system,
- W is the work done by the system.
Work Done in Isothermal Process (Ideal Gas)
W = nRTln(Vf/Vi)
Where:
- W is the work done,
- n is the number of moles of gas,
- R is the ideal gas constant,
- T is the temperature,
- Vf is the final volume,
- Vi is the initial volume.
Heat Transfer (Constant Pressure)
Q = nCp ΔT
Where:
- Q is the heat added or removed,
- n is the number of moles of gas,
- Cp is the specific heat at constant pressure,
- ΔT is the change in temperature.
Ideal Gas Law
PV = nRT
Where:
- P is the pressure of the gas.
- V is the volume of the gas.
- n is the number of moles of gas.
- R is the gas constant.
- T is the temperature of the gas.
Entropy Change
ΔS = Q/T
Where:
- ΔS is the change in entropy.
- Q is the heat.
- T is the temperature.
Gibbs Free Energy
ΔG = ΔH − TΔS
Where:
- ΔG is the change in Gibbs free energy,
- ΔH is the change in enthalpy,
- ΔS is the change in entropy, and
- T is the absolute temperature
List of Physics Formulas
Physics is a fundamental branch of science that studies matter, its fundamental constituents, and its motion and behavior through space and time. Physics Formulas are very important during applications of various concepts of physics.
