Non size-scale scaling law

This page is about scaling laws for other possible other parameters beside size.
For scaling laws over size scales see: Scaling law – or: Scaling law (disambiguation).

This more general treatment kinda seems to blur into just about any physical laws.
Well; Especially worth being called a scaling law are laws that seem

• laws that are quite simple
• laws that are polynomial
• laws with a relationship between two quantities that stands out especially
  (when it is sensible to keep all other involved quantities constant)

Examples

Scaling laws over temperature

• Stefan Boltzmann law. Thermal radiation rises to the fourth power with temperature. – (wikipedia)
• ...

Scaling laws over pressure

• Quantity of viscous flow of a liquid through a pipe of constant diameter and constant length depending on pressure.
