4A.3

Can someone please explain this problem. The solution manual is using 101.325J as a conversion but I'm not sure where they are getting it from. Other than that, I still don't understand the problem.

Re: 4A.3

The purpose of using 101.325 is to convert atm to Pa. In SI units, Pa is J.m^-3 . The equation used is w=PAD, and work is in joules, so the units would essential cancel out to joules because w=(J.m^3)(m^2)(m) .

You can find this number in the constants and equations paper. It converts 1 Latm to 101.325 J.

The textbook explains that the number comes from converting L*atm to Joules.
