The axes of any phase diagram have temperature (x-axis) and pressure (y-axis).
With a temperature of 273K and a pressure of 101.325 kPa , water is at its freezing point.
Now keeping the same temperature (273K) , but reducing the pressure to say , 100 Pa ,water will be a gas.
Conversely, at a temperature of 373K and 101,325 kPa water is at its boiling point. However, if you increase the pressure to say 10 MPa, water remains a liquid. If you keep the same temparture 373 K and increase the pressure to 10GPa then water remains a solid.
Another way is to randomly select any given point on the phase diagram, say in the Gas phase and read the temperature and pressure.

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 state is the substance in if a phase diagram shows the substance is in the state at 1 ATM and -50C?
The substance is in the solid state at 1 ATM and -50°C based on the phase diagram.
At a given temperature and pressure the physical state of a substance is determined by?
It's determined by the spacing of its atoms. If they are spaced close together in a rigid formation it's a solid. Somewhat spread out and fluid in formation is a liquid. Spaced far and very active in its motion is a gas.
What is the difference between solidus and solvus?
The solidus is the boundary line on a phase diagram that separates regions where a substance is in a solid state from where it is in a liquid state. The solvus is the boundary line on a phase diagram that separates regions where solid solutions are stable from regions where they are not stable, indicating the limited solubility of one component in another.
Using the phase diagram for CO2 what phase is carbon dioxide in at -60C and 15 ATM pressure?
(Explanation): If you look at the phase diagram for CO2, and you draw a lines where the temperature and pressure meet, you will see that the point will be inside the zone that is 'solid', so it is in the solid state.

What diagram shows the change that produces glass?
The diagram that typically shows the change that produces glass is called a "phase diagram" or "phase transformation diagram." It illustrates the transition from a liquid state to a solid state as the temperature and composition change, highlighting the process of cooling molten silica and other materials to form glass. The diagram often includes regions representing different phases (solid, liquid) and critical points where the transitions occur.

What is a phase diagram of a differential equation?
A phase diagram of a differential equation is a graphical representation that illustrates the trajectories of a dynamical system in the state space defined by its variables. Each point in the diagram corresponds to a particular state of the system, with arrows indicating the direction of movement over time based on the system's behavior. Phase diagrams help visualize stability, equilibrium points, and the overall dynamics of the system, making them essential tools in understanding the qualitative behavior of differential equations.
What is a graph of the relationship between the physical state of a substance nad the temperature and pressure of a substance?
A phase diagram illustrates the relationship between the physical state (solid, liquid, gas) of a substance and its temperature and pressure. Different regions on the diagram correspond to different states of matter based on the prevailing conditions of temperature and pressure. The boundaries between the regions represent conditions where phase transitions occur.
Indicate the type of state change that occurs between each pair of points on the following phase diagrare you to e?
The diagram needs to be seen to know what the state of change is. Not seeing the diagram makes people not able to know what the change would be.
What best describes the change directly from the solid phase to the gas phase?
The change directly from the solid phase to the gas phase is called sublimation. This transition occurs when a substance goes from a solid state to a gaseous state without passing through the liquid state.
What is the significance of degrees of freedom in a phase diagram?
In a phase diagram, degrees of freedom represent the number of variables that can be independently controlled to specify the state of a system. The significance of degrees of freedom lies in their ability to determine the number of phases that can coexist in equilibrium at a given temperature and pressure. By understanding the degrees of freedom, scientists can predict the behavior of a system and its phase transitions.
