How much work is done on a system when an ideal gas is expended adiabatically from 0.4 liters to 2.4 liters under constant pressure of 1.25 atmosphere?
A. 5
B. 2.5
C. -2.5
D. -5
I thought the answer should have been B because "work is done on a system"; therefore, work should positive...but the book (BR) says the answer is C.
