In graphs, how high and how far right a point is describe its properties. Like the phase diagram of water: the further right you are, the higher the temperature, the further up you are, the higher the pressure. At each point, water would be in a certain state, which is plotted on the graph as colored areas.
Axes are markings that only help measure how hot and pressurized a certain point is. You are probably at around 100 kPa (atmospheric pressure) and 295 K (room temperature) so you experience liquid water. Even though the vertical axis is labeled “Pressure”, that does not mean pressure only exists on that line; same for the temperature axis. These meet at absolute zero in near-vacuum. Even though you pr But you might prefer axes at 0 °C (the left vertical red line) and 1 atm (the horizontal red line).
@ChaoticNeutralCzech don’t get it
