Question:

The graph in Fig. P19.48 shows a pV-diagram for 3.25 moles of ideal helium (He) gas. Part ca of this process is isothermal.

(a) Find the pressure of the He at point a.

(b) Find the temperature of the He at points a, b, and c.

(d) By how much did the internal energy of the He change from a to b, from b to c, and from c to a? Indicate whether this energy increased or decreased.
