3)the area under a temperature versus entropy graph gives heat added or taken out of a system for the process connecting the initial andfinal states on a tsdiagram.(a)plot the initial state and final state of the process described in fnt 2 as points on a tversus sgraph. assume that the initial entropy had an absolute value of 4,800j/k.(b)explain why the processthat connects the initial state and final state must be a straight horizontal line segment.(c)show that the amount of energy transferred as heat into the co2system is the same as the area under the tscurve. describe ingeneral what features of a tsdiagram tell you whether energy was either transferred into (+q) or out of (–q) a system.(d)why is the absolute value of temperature important on a tsdiagram, but the absolute value of entropy on a tsdiagram can be arbitrarily set (as was done )consider the three types of diagrams that can be used to describe the processes that connect an initial state of a system to its final state: pvdiagrams, cptdiagrams, and tsdiagrams. what do you notice about the units of multiplying p·vtogether, multiplying cp·ttogether, and multiplying t·stogether?
