The enthalpy of vaporization of ethanol is 38.7 kJ/mol at its boiling point $\left({78}^{\circ}C\right)$ . Determine $\mathrm{\u25b3}{S}_{sys},\mathrm{\u25b3}{S}_{surr},{\textstyle \phantom{\rule{1em}{0ex}}}\text{and}{\textstyle \phantom{\rule{1em}{0ex}}}\text{}\mathrm{\u25b3}{S}_{univ}$ when 1.00 mole of ethanol is vaporized at ${78}^{\circ}C$ and 1.00atm.

You can still ask an expert for help

If the U-Shaped conductor in fig below has resisted ?, whereas that of the moving rod is negligible, derive a formula for the current I as a function of time. Assume that the rod has length l, starts at the bottom of the U at t=0, and moves with uniform speed v in the magnetic field B. The cross-sectional area of the rod and all parts of the U is A.
