One mole of an ideal gas with 
expands from 
and 
bar by each of the following paths:
(a) Constant volume; (b) Constant temperature; (c) Adiabatically. Assuming mechanical reversibility, calculate W, Q, ?U, and ?H for each process. Sketch each path on a single PV diagram.
Find a 99% confidence interval for the difference between the proportions of eggs that hatch at the two sites.
The article “Genetically Based Tolerance to Endosulfan, Chromium (VI) and Fluoranthene in the Grass Shrimp Palaemonetespugio” reported that out of 1985 eggs produced by shrimp at the Diesel Creek site in Charleston, South Carolina, 1919 hatched, and at the Shipyard Creed site, also in Charleston, 4561 out of 4988 eggs hatched.
A delta-connected source supplies power to a wye-connected load in a three-phase balanced system. Given that the line impedance is 2 + j1 ? per phase while the load impedance is 6 + j4 ? per phase, find the magnitude of the line voltage at the load. Assume the source phase voltage Vab = 208?0? V rms.
