What is the the triple point on a phase diagram?
The triple point of a phase diagram is the location where the solid, liquid, and gas phases meet; it is the temperature and pressure at which a given substance can assume any of the 3 usual phases of matter.
Which of the statements about the triple point is true?
it is a property of substances. it is the temperature and pressure at which all three states of a substance coexist it is easily identified from a phasediagram (apex answer)
Using the phase diagram for CO2, what phase is carbon dioxide in at 12 atm pressure and -40 C apex?
At 12 atm pressure and -40°C, carbon dioxide is in the solid phase according to the phase diagram. This corresponds to the region of the phase diagram where CO2 exists in the solid state at those specific pressure and temperature conditions.
What do the lines on a phase diagram represent?
The lines on a phase diagram represent the boundaries between the different phases of a substance (such as solid, liquid, and gas). These lines show the conditions of temperature and pressure at which two phases can exist in equilibrium with each other.

a diagram showing the effects of temperature and pressure on phase

Using the phase diagram for CO2 what phase is carbon dioxide in at -20C and 1 ATM pressure?
The triple point of Carbon Dioxide is 216.55 K (−56.60 °C) and 517 kPa (5.10 atm). Since that puts the pressure (1 atm) below the triple point pressure (5.1 atm) we are only concerned with the where the solid/vapor equilibrium line falls relative to the temperature. At 1 atm, the sublimation temperature of Carbon Dioxide is -78.5 °C - considerably below -20 °C so that puts the Carbon Dioxide firmly in the vapor region of the phase diagram.

At 12 atm pressure and -40°C, carbon dioxide is in the solid phase according to the phase diagram. This corresponds to the region of the phase diagram where CO2 exists in the solid state at those specific pressure and temperature conditions.
Which of the choices describes a boiling point?
There is no boiling point in the p,T diagram: it is a line between the vapor and liquid phase.Cf. phase diagram in 'Related links' just below this answer][The simplest phase diagrams are pressure-temperature diagrams of a single simple substance, such as water.The axes correspond to the pressure and temperature.The phase diagram shows, in pressure-temperature space,the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas.]

Using the phase diagram for H2O, which of the following correctly describes water at 0°C and 1 atm?
At the melting point (Explanation) if you look at the phase diagram and look at the point where the water is 0 degrees C and 1 atm, they meet right on the line. This is the line that shows the melting point of this substance. Therefore, since the point is on the line, water at 0 degrees C and 1 atm is at the melting point.
What happens at the triple point of water?
Solid, liquid, and gas exist together. Apex
