Problem 7.1 What temperature drop in the water in the oceans would be needed to supply the energy used in the USA in one year if we could violate the Kelvin statement of the second law and obtain all of that energy from the oceans as heat without any other effect? Use US engineering units throughout. Do not change to metric units. In engineering practice $Q = wc_p \Delta T$, where $w$ is weight and $c_p$ has units of Btu lb$^{-1}$ $^\circ$F$^{-1}$. Data: 1 mile = 5280 ft; volume of the oceans, $3.29 \times 10^8$ mile$^3$; density of sea water, 64 lb ft$^{-3}$; specific heat of sea water, $c_p = 1.0$ Btu lb$^{-1}$ $^\circ$F$^{-1}$; the U.S. used approximately $9 \times 10^{16}$ Btu of energy annually from 2004 to 2010.

10. We saw several examples of polymer surface restructuring in class, both for solid chunks of polymers and for surface-grafted polymers. Perform a literature search and find another example of this phenomenon (not one of the examples in the notes or text). Give the full citation (title, authors, journal name, year, volume, and page #s) and briefly describe the surface restructuring that occurs. Include a drawing to help illustrate the restructuring.
