Finding out pressure in a container if you know temp' and state-of-matter ratios

Click For Summary
SUMMARY

The discussion centers on determining the pressure in a container containing water at 150 Celsius, given the temperature and the ratio of gas to liquid. Participants confirm that utilizing a phase diagram allows for accurate pressure estimation when these parameters are known. The phase diagram provides a visual representation of the states of matter and their corresponding pressures at various temperatures. This method is established as a reliable approach in thermodynamics.

PREREQUISITES
  • Understanding of phase diagrams in thermodynamics
  • Knowledge of the properties of water at different temperatures
  • Familiarity with the concept of state-of-matter ratios
  • Basic principles of pressure measurement in closed systems
NEXT STEPS
  • Study the construction and interpretation of phase diagrams for various substances
  • Research the properties of water at high temperatures, specifically above 100 Celsius
  • Explore the relationship between temperature, pressure, and state of matter in thermodynamics
  • Learn about the Clausius-Clapeyron equation for phase transitions
USEFUL FOR

Chemists, physicists, and engineers involved in thermodynamic analysis, as well as students studying physical chemistry and material science.

Let's say you have a container with water in it. Let's say that you know that the temperature inside the container is 150 Celsius. Let's say that you have the ability to see inside the container and see the ratio of gas to liquid.

So, if you know the ratio and know the temperature, can you find out the pressure then by just looking at a phase diagram?

I would assume so if you had all the required values other than the pressure.
 
Ah...chemistry. It just makes sense. Thanks :)
