Chapter 3: Q52P (page 644)
A certain ideal gas has molar heat capacity at constant volume CV. A sample of this gas initially occupies a volume V0 at pressure p0 and absolute temperature T0. The gas expands isobarically to a volume 2V0 and then expands further adiabatically to a final volume 4V0. (a) Draw a pV-diagram for this sequence of processes. (b) Compute the total work done by the gas for this sequence of processes. (c) Find the final temperature of the gas. (d) Find the absolute value of the total heat flow /Q /into or out of the gas for this sequence of processes, and state the direction of heat flow.
Short Answer
(a)In the first process pressure remains constant and in the second process it reduced adiabatically.
(b) the total work done by the gas for this sequence of processes is
(c) the final temperature of the gas is
(d) the absolute value of the total heat flow 0 Q 0 into or out of the gas for this sequence of processes is
