Use this phase diagram to answer the questions which follow: A. When the pressure is 7.1atm and temperature is 9.0C, we would expect this compound to be a solid liquid gas supercritical fluid B. Select the statement below that is true. the density of the solid and the liquid are the same. the density of the solid is greater than the density of the liquid. the density of the solid is less than than the density of the liquid. not enough information given. C. Identify the critical point in the phase diagram. P=T=atmC
