Chapter 19, Problem 19.59

(choose chapter or problem)

You have recorded measurements of the heat flow Q into 0.300 mol of a gas that starts at \(T_1 = 20.0^\circ \mathrm C\) and ends at a temperature \(T_2\). You measured Q for three processes: one isobaric, one isochoric, and one adiabatic. In each case, \(T_2\) was the same. Figure P19.59 summarizes your results. But you lost a page from your lab notebook and don’t have a record of the value of \(T_2\); you also don’t know which process was isobaric, isochoric, or adiabatic. Each process was done at a sufficiently low pressure for the gas to be treated as ideal. (a) Identify each process a, b, or c as isobaric, isochoric, or adiabatic. (b) What is the value of \(T_2\)? (c) How much work is done by the gas in each process? (d) For which process is the magnitude of the volume change the greatest? (e) For each process, does the volume of the gas increase, decrease, or stay the same?
