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

AI Thread Summary
To determine the pressure in a container with water at 150 Celsius, knowing the gas-to-liquid ratio and temperature allows for the use of a phase diagram. The phase diagram provides critical data on the relationship between temperature, pressure, and the state of matter. By identifying the specific point on the diagram that corresponds to the given temperature and phase ratio, the pressure can be inferred. This method relies on accurate phase diagrams that reflect the properties of water under varying conditions. Understanding these relationships is essential in chemistry for predicting system behavior.

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 :)
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
