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?
