Quantities that are independent of the size of a system are _intensive variables_. # List of Intensive variables It may seem obvious which variables are intensive, but it's good to list them just in case, because there are a lot of them and keeping track of these things helps with problem solving. * Temperature, $T$ * Pressure, $P$ * [[chemical potential]], $\mu$ * density, $\rho$ * While [energy](Thermodynamic%20energy.md) is [extensive](extensive%20variables.md) #StatisticalPhysics
