Ideal Gas Law
- Gases obey the gas laws at low pressures and at temperatures above those at which they liquefy.
- An ideal gas will obey:
- where
- p = Pressure
- V = Volume
- n = Number of moles
- R = Molar gas constant
- T = Temperature
- V = Volume
- An ideal gas will also obey the following laws:
- Joule's law
- Boyle's law
- Adiabatic equations
- Internal energy
- Reversible isothermal expansion
- Joule expansion
- where
- U = Internal energy
- γ = Ratio of heat capacities
- ΔW = Work done on system
- ΔQ = Heat supplied to system
- ΔS = Change in entropy of the system
- γ = Ratio of heat capacities
- Note: subscripts 1 and 2 denote initial and final states respectively.
