1. Mark with T (True) or F (False) (2 points each) • Joule Thompson experiment corresponds to process with constant enthalpy. . The state functions (U.H,G,A) act as thermodynamic potentials when represented as functions of their natural variables. • The Gibbs free energy is equal to the maximum PV work done by the system on the envi- ronment. . The standard enthalpy of formation for any...
Need help filling in my data sheet from a lab. My professor said
the pressure was 24.6 inches of Hg and that we needed to convert
that to moles. Im not sure i put that in the correct spot. I
included the lab protocol. Plz plz plz help me fill in the blanks
and let me know if i did something wrong Im very confused haha.
THANKS!!
