Gas mixture pressure from partial pressures =========================================== The pressure of a mixture of gases is equal to the sum of their partial pressures. *Partial pressure* of a gas is the pressure that the gas would exert on the walls of a vessel when it is the only gas present in the vessel. **Links:** #. `Wikipedia `__. .. py:currentmodule:: symplyphysics.laws.thermodynamics.gas_mixture_pressure_from_partial_pressures .. py:data:: total_pressure Total :attr:`~symplyphysics.symbols.classical_mechanics.pressure` inside the system.
