Extensive and Intensive Quantities
Extensive quantity: its magnitude is additive for subsystems (volume, mass, etc.)
Intensive quantity: the magnitude is independent of the extent of the system (temperature, pressure, etc.)
There are also physical quantities that can be classified as neither extensive nor intensive, for example angular momentum, area, force, length, and time.

“The Walrus and the Carpenter
Were walking close at hand:
They wept like anything to see
Such quantities of sand:
“If this were only cleared away,”
They said, “it would be grand!”
“If seven maids with seven mops
Swept it for half a year,
Do you suppose,” the Walrus said,
“That they could get it clear?”
“I doubt it,” said the Carpenter,
And shed a bitter tear.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
