INFORMATION:
We know that:
- in a sample of liquid argon the pressure is reduced from 10 atmospheres to 1 atmosphere at a constant temp of 100 K
And we must describe the changes argon will have
STEP BY STEP EXPLANATION:
To answer the question we can use the graph of the phase diagram to answer the question
The phase the diagram of the argon using that the normal boiling and freezing points of argon are 87.3 K and 84.0 K, respectively, the triple point is at 82.7K and 0.68 atmosphere would be
If we look for the point when the temperature is 100K and the pressure is 1 atm when can see that the state of argon would be gas. The change that the argon will have would be a change in its state from liquid to gas.
ANSWER:
The change that the argon will have would be a change in its state from liquid to gas. That means the argon vaporizes when the pressure is reduced from 10 atmospheres to 1 atmosphere at a constant temp of 100 K
