Direction: Visualize a substance with the following points on the phase diagram: a triple point at 0.05 atm and 150 K; a normal melting point at 175 K; a normal boiling point at 350 K; and a critical point at 2.0 atm and 450 K. The solid liquid line is "normal" (meaning positive sloping). For this, complete the following: Constructing a Phase Diagram Roughly sketch the phase diagram, using units of atmosphere and Kelvin. Label the area 1, 2, and 3, and points T and C on the diagram. Describe what one would see at pressures and temperatures above 2.0 atm and 450 K. Describe the phase changes from 50K to 250 K at 1.5 atm. What exists in a system that is at 1 atm and 350 K? What exists in a system that is at 1 atm and 175 K?

Need answers for the blue parts,thank you!!

d• Using the phase diagram to the right, select all of the statements that are false. f Te Temperature (not to scale) Point G is the Critical Point. The substance is a supercritical fluid at Point F Decreasing the pressure of the substance at constant Temperature from point A, will result in vaporization Cooling the substance at Point F will induce condensation There is an equilibrium in the gaseous and liquid states at Point E. Increasing the temperature at constant pressure from Point A will results in two phase changes in the substance. Pressure (not to scale)

Use the phase diagram of Substance X below to find the pressure at which the boiling point of X is 64.°C     Note: your answer must be within 0.025atm of the exact answer
