Hi Everyone,
...
"Another change for 2002 relates to the sign convention used for work=
in thermodynamics. In thermodynamic equations, the symbol W will rep=
resent the work done on a system rather than by a system, so that the=
first law of thermodynamics will be written D U =3D Q + W. This chan=
ge makes the sign convention consistent with that used for work in me=
chanics, as well as with the thermodynamic convention used in most ch=
emistry and some physics textbooks."
For example, is the dV in the work integral (for work done "on" the system)
now changed from negative to positive ??? Or vice versa ??
This goes against the standard mathematical dV representing an "increase" in
V.
