There are two processes ABC and DEF. In which of the processes is the amount of work done by the gas greater ?
|
ABC DEF Equal in both processes It cannot be predicted |
DEF |
\(W_{ABC} = \frac{\pi r^2}{2} = \frac{\pi 6^2}{2} = 18 \pi\) \(W_{DEF} = \frac{\pi*3^2}{2} + \frac{\pi *3^2}{4} + (15-12)*18 = 6.75 \pi + 54\) \(W_{DEF} > W_{ABC}\) |
