These include astrophysics (physics of astronomy), geophysics (physics of geology), biophysics (physics of biology), chemical physics (physics of chemistry), and mathematical physics (mathematical theories related to physics).

Other equations of state may be used, such as the van der Waals equation of state, that takes into account the finite size of the atoms or molecules making up the gas, and the intermolecular forces between nearby molecules:
