A volume of air (assumed to be an ideal gas) is first cooled without changing its volume and then expanded without changing its pressure, as shown by the path abc in the figure (Figure 1). Take the values p=2.5×10^5Pa and V=0.05m3. If the air instead expands from state a to state c by the straight-line path shown, how much heat does it exchange with its surroundings?
