    But the system also gets smaller. Isnâ€™t it therefore the case that the increased heat is an expression of energy density increasing at the expense of the volume of the system, which shrinks so much that the total energy content of the system is still smaller than it started out, even though the density has increased?

    So to make the analogy with the open front door correct, in a house where leaving the front door open caused it to heat up, doing so would primarily cause the house to deflate. And it would shrink fast enough that even though heat was draining from it, it would still heat up.

    Ah, I guess that is what motivated your remark on the spendthrift principle of nature.
