## Energy Extensive or Intensive?

isochoric/isometric: $\Delta V = 0$
isothermal: $\Delta T = 0$
isobaric: $\Delta P = 0$

### Energy Extensive or Intensive?

I was looking at an old quiz and it asked if energy was extensive or intensive.
What is the difference between the two?

Extensive properties depend on the amount of material or the size of the sample (moles, mass, volume, etc.). Intensive properties, on the other hand, do NOT depend on the the amount of material available, like density, pressure, color, etc.
Energy does depend on the amount of stuff in the system, so it is extensive.

Adding on, some examples of intensive properties include specific heat capacity and standard reduction potential, whereas examples of extensive properties include entropy, enthalpy, and Gibbs free energy. Standard reduction potential $E^{\circ}$ being an intensive property is the reason why for redox reactions the value of $E^{\circ}$ does not change when the half-reactions are being balanced.
