A)energy is released when a block of granite cools from 373 k to 293 k. what is the ratio of this energy to the potential energy it would lose in falling through a distance of 540 m to the surface of the earth? the specific heat capacity of granite is 796 j k-1 kg-1 b)a carnot engine has an efficiency of 16.7 % with its hotter reservoir at a temperature 323 k. what must the temperature of its cooler reservoir be? if the same engine is operated in reverse as a refrigerator, what is its performance value? c)this question concerns two hypothetical gases miltonium and keynesium whose molecular masses are such that keynesium is 9x more massive than miltonium. imagine that 3 moles of each gas are put into separate identical containers and that the pressure in the miltonium is 4x that in the keynesium. assuming ideal behaviour in both gases what would be the ratio of the root-mean-square speed of the molecules of miltonium to that of the molecules of keynesium d)two electrons each with a momentum of magnitude about 10-23 kg m s-1 are traveling along the x-axis, approximately 1 nm apart. they pass a measurement device which determines their momentum. to what precision can the momentum be deternmined without losing the ability to clearly recognize that two distinct particles have passed? (observations of two distinct particles requires that the wavefunctions representing the two electrons do not overlap apprecialbly.)
