How to calculate K or Q without one or the other? For example, if the material is unknown (but cannot test density, or melting temperature) how would you test heat flux? Q=K(Th-Tc)/(x)

Thank you for the reply. To make sure I understand the concept, when calculating ## \Delta U ## the heat of vaporization does not need to be added, because the calculation already accounted for it? I am also somewhat confused with this outcome for Work because I thought that work done ON a...

First, I did find a previous discussion from a few years ago related to this problem. However, my specific question is further along in the problem than the other person got: Homework Statement A piston-and-cylinder device contains 5 kg of water initially at 150 ◦C and 0.20 MPa. The...
