a: heat ~
b: the amount of water in a towel
What:
"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 "

a: heat ~
b: jiggling molecules
What:
or maybe vibrating. Stuff that is hot,relative to people, have molecules that are jiggling very rapidly relative to cooler stuff in which molecules are jiggling relatively slowly.

a: wheat genome ~
b: solving a jigsaw puzzle
What:
"The bread wheat is a difficult organism to sequence because its genome is large - about six times the size of the human genome - and it is difficult to assemble because of its unusual ancestry. It is hexaploid, containing six sets of chromosomes derived from three different ancestors. In other words, assembling the bread wheat genome is like solving a jigsaw puzzle made up of three similar, but different sets of jigsaw puzzles."

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."

Inertia Is Every Where.....
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."
