By Density Or Volume?
a: Heat capacity ~
b: modulus or melting point
What: "Heat capacity is like modulus or melting point - it depends on the stiffness and strength of atomic bonds. There's not much you can do about these, so the heat capacity per unit weight, , for a given material, is beyond control. The heat capacity per unit volume, , on the other hand can be reduced just by changing the density - by making a porous or foam-like structure - useful when you want a structure that will heat up or cool down quickly."

METAMIA is a free database of analogy
and metaphor. Anyone can contribute or search.
The subject matter can be anything.
Science is popular, but poetry is encouraged.
The goal is to integrate our fluid muses with
the stark literalism of a relational database.
Metamia is like a girdle for your muses,
a cognitive girdle.
