The solid and gas phases are in equilibrium at -78.7 °C and 1.00 atm. Which of the following statements regarding CO2 is/are CORRECT? On the phase diagram below, which point corresponds to conditions where only the solid phase exists? On the phase diagram below, which point corresponds to conditions where both liquid and gas phases exist?
a) Point A corresponds to sublimation/deposition. b) Point B corresponds to the critical point, where all three phases coexist. c) Point C corresponds to the liquid phase of the substance. supercritical fluid. condense. b) Point B corresponds to the critical point, where all three phases coexist. LiCl, H2S.
The phase diagram for CO2 has a triple point at -56.6 °C and 5.19 atm, and a critical point at 31.0 °C and 73 atm. The solid and gas phases are in equilibrium at -78.7 °C and 1.00 atm. Which of the following statements regarding CO2 is/are CORRECT? On the phase diagram below, which point corresponds to conditions where only the solid phase exists?
The letters indicate specific points in the phase diagram. In going from point A to H to C, what phase transitions does X undergo? The triple point of iodine is at 90 torr and 115°C.
The line crosses the line between points B and C at the boiling point of the substance because the normal boiling point of a liquid is the temperature at which the liquid and gas are in equilibrium at 1 atm pressure and the vapor pressure of the liquid is therefore equal to 1 atm.
The normal melting and boiling points are those when the pressure is 1 atmosphere. These can be found from the phase diagram by drawing a line across at 1 atmosphere pressure.
The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).
The normal melting point of a substance is its melting point at a pressure of 1 atm. For a pure substance, the freezing point of the liquid equals the melting point of the solid. For pure water, the normal melting point is 0.0024 °C.

Now the normal melting and the normal boiling points, by definition are the temperatures at which the solid changes to liquid, and the liquid changes to gas at ONE ATMOSPHERE . So simply draw a horizontal line on the y axis, and note the x intercepts of the transitions to give these properties.
1 The normal freezing point(a) and triple point (b) of water. The total pressure on the contents of this container is 1 atm (101.3 kPa) and its temperature is exactly 273.15 K (0.00°C). As far as liquid and solid are concerned, this corresponds to point F in the phase diagram.
The boiling point of a pure substance is the temperature at which the substance transitions from a liquid to the gaseous phase. At this point, the vapor pressure of the liquid is equal to the applied pressure on the liquid. The boiling point at a pressure of 1 atmosphere is called the normal boiling point.
