Thermodynamics - Chapter 4 - Boundary Work Exercises Part 1

[josephisrael]

If the cylinder's volume was 60% at the final state, why wasn't the 60% figure also used in part a?

[nabiyevali]

in question 1 we should have negative boundary work -22.19kJ, why you took it positive?

[frederickabiiro]

why is v2 subtracted from v1 is it a special case when using specific volumes?for the first case

[deadlysilent]

the work should be negative because it is compression
