Cubic equations for specific heat
The table of specific heat capacities gives the volumetric heat capacity as well as the specific heat capacity of some substances and engineering materials, and (when applicable) the molar heat capacity. Generally, the most notable constant parameter is the volumetric heat capacity (at least for solids) which is around the value of 3 megajoule per cubic meter per kelvin: WebJan 13, 2024 · Once these are determined, the van der Waals equation, itself, allows us to determine the critical pressure, Pc. To solve the equations, first divide one by the other. This gives us a simple condition for the volume: Vc − nb 2 = Vc 3 3Vc − 3nb = 2Vc Vc = 3nb. This is the critical volume.
