Chuck thinks they ought to buy both a toaster and toaster oven. he often fixes his own breakfast early in the morning, and he thinks toast from the toaster taste better. he wants a toaster oven to warm up small amounts of other foods. mr. wiley says they can't have both because they would take up too much counter space. point out any false reasoning that you find. you may recommend one of the items they mention, or suggest something entirely different.

I) a gas contained within a piston-cylinder assembly undergoes two processes, a and b, between the same end states, 1 and 2, where p1 = 10 bar, v1 = 0.1 m3 , u1 = 400 kj and p2 = 1 bar, v2 = 1.0 m3 , u2 = 200 kj: ' process a: process from 1 to 2 during which the pressure-volume relation is pv = constant. ' process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to state 2. kinetic and potential energy effects can be ignored. for each of the processes a and b, a) sketch the process on a p-v diagram. b) evaluate the work, in kj. c) evaluate the heat transfer, in kj.(ans : qb,12 = -65.0 kj)
