A monatomic ideal gas undergoes isothermal expansion from 0.08 m3 to 0.22 m3 at a constant temperature (initial pressure is 310 kPa). What are its (a) internal energy change (ΔEΔE), (b) net heat transfer (Q), and (c) net work done (W)? Use negative quantity for heat transfer out of the system or work done on the system.
Homework Answers
