Problem: The melting point of a fictional substance X is 225 ˚C at 10.0 atm. If the density of the solid phase of X is 2.67 g/cm3 and the density of the liquid phase is 2.78 g/cm 3 at 10.0 atm, predict whether the normal melting point of X will be less than, equal to, or greater than 225 ˚C. Explain.

🤓 Based on our data, we think this question is relevant for Professor Goodey's class at TAMU.
