What is a universal expansion rate?

When most fluids are heated, part of that is absorbed and heats up the fluid and part of the energy causes the fluid to expand. How much it assorbs of course depends on the over all mass, but the difference between how much is and how much is turned into expansion depends on the heat ratio. A low heat ratio causes the fluid to expand very little but heat up a lot of atoms for every BTU.
