a: heat ~
b: the amount of water in a towel
"A useful physical analogy is Feynman's - heat is like the amount of water in a towel, while temperature is the "wetness." Given two towels of the same "wetness" the bigger one contains more water. A small towel can be much "wetter" but contain less water than a big towe "

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."

a: Heat conductivity ~
b: suspension on your car
What: "The more thermal mass (heat capacity) the pot has, the more slowly it will change temperature, even if it's a good heat conductor. As an analogy, I'll use cars, something I have on my mind right now because of the gigantic frost heaves in our local roads at this time of year. Heat conductivity is like the suspension on your car: good heat conduction is like a stiff suspension that "lets" you feel every bump in the road; poor heat conduction is more like a nice soft suspension with good shock absorbers. Thermal mass (heat capacity) is like the weight of your car: the heavier it is, the less it will jump up and down with the bumps; the more heat capacity, the more heat the pot soaks up before it changes temperature. So, when I drive down the road in our heavy company pickup with cushy suspension, I hardly feel the bumps."

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.
