Chapter 12.4, Problem 33SSC

Interpretation Introduction

Interpretation:

The phase of water must be determined at 75.00°C and 3.0 atm pressure from the given phase diagram.

Concept introduction:

Phase diagram is a graphical representation of the phase change of a substance along with temperature and pressure. The phase of a substance at a particular temperature and pressure can be determined from phase diagram.

Answer to Problem 33SSC

Phase of water is liquid at 75.00°C and 3.0 atm pressure.

Explanation of Solution

As can be seen from the phase diagram from 0°C to 100°C and upto 217.75 atm pressure water is in liquid state. As the given temperature is 75°C which is in between 0°C and 75°C and given pressure is 3 atm which is in between 1 atm and 217.75 atm thus water will be in liquid state.

Conclusion

There will be liquid water at 75°C and 3 atm pressure.
