Hi,

I was working on my hwk, but would like to double check my answer. Could you please solve it?

H3.7 (Ideal Gas) A piston-cylinder device contains 1.5 kg of O2 initially at 300 kPa and 647 C. The gas is cooled at constant pressure until its volume is one-third of the original volume. Assume ideal gas behavior with variable specific heats and negligible kinetic and potential energy effects. a. work (kJ) during process (indicate magnitude and direction) b. heat transfer (kJ) during process (indicate magnitude and direction)
