Density is simply the amount of "stuff" in a given space. Scientists measure density by dividing the mass of something by its volume (d = m/v). This is a story about how the concept of density was first "discovered." 2 It is the story of a Greek mathematician named Archimedes who lived around ...

WebAbstract. Organisms are non-equilibrium, stationary systems self-organized via spontaneous symmetry breaking and undergoing metabolic cycles with broken detailed balance in the environment. The thermodynamic free-energy (FE) principle describes an organism’s homeostasis as the regulation of biochemical work constrained by the physical FE cost. Web1 / 17. Volume: amount of space a substance or object occupies. Density: the degree to which something is compacted. They relate to each other because: Density = the quantity of mass per unit volume. Density Formula. Density = mass/volume. Volume units: Liquid: Liters (L) or Gallons.
