Chapter 16, Problem 13P
* Rolling dice Two dice are rolled Macrostates of these dice are distinguished by the total number for each roll (that is, 2, 3, 4..., 12). (a) Determine the number of microstates for each macrostate. For example, there are three microstates for macrostate 4 (2, 2), (3,1), and (1, 3). (b) What is the macrostate with greatest entropy? (c) What is the macrostate with least entropy? Explain.

Problem 1
A rectangular tank that is 4 feet long, 7 feet wide, and 9 feet deep is filled with a heavy liquid that weighs 60 pounds per cubic foot. In each part below, assume that the tank is initially full. Include correct units.
c) How much work is done pumping two-thirds of the liquid out over the top of the tank?
d) How much work is done pumping two-thirds of the liquid out of a spout 2 feet above the top of the tank?

1 Deep Impact
It is widely accepted that a meteor impact 65 million years ago caused a mass extinction of life on our planet, relegating
the dinosaurs to the fossil record. The meteor was about 5 miles in diameter and moving at about 20 miles per second
relative to the earth.
Assume the density of the meteor was similar to that of the earth, about 5.5 g/cm³.
(a) The meteor was vaporized during the impact and virtually all of its kinetic energy was converted into heat. How
much energy was released as heat? Report your result in joules (J).
(b) This was an inelastic collision: (The meteor ended up as a layer of dust about half an inch thick covering the entire
planet.) How much did the velocity of the earth change as a result of the impact?
Problem 2
A rectangular tank that is 88 feet long, 33 feet wide, and 1515 feet tall is filled with a liquid that has a density of p pounds per cubic foot. If a spout is connected to the top of the tank, how much work will it take to pump all of the liquid out of the tank through the spout?
Work= ____________ft-lb
How much work will it take to pump all of the liquid out of the tank through a spout that is T feet above the top of the tank?
Work= ____________ft-lb
Answers should be in terms of p and T.
