How much heat is needed to vaporize 33.3 grams of ethyl alcohol at its boiling point of 78.0°c? the latent heat of vaporization of ethyl alcohol is 857 j/g. round your answer to three significant figures. joules

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

Which transition by an electron will release the greatest amount of energy? oa ob oc od

If we relied solely on the nonrenewable resources found in the u.s., which one would we run out of first at current usage levels? a. natural gas b. oil c. uranium d. coal
