Calculation of volume after phase change

Click For Summary
SUMMARY

The discussion focuses on calculating the volume of a gas at a specific temperature compared to its liquid volume below the boiling point. John suggests using the ideal gas law, represented as PV = nRT, to determine the gas volume. To find the number of moles (n), one can utilize the liquid's volume and density. The conversation highlights the importance of understanding phase changes and the ideal gas law in these calculations.

PREREQUISITES
  • Ideal Gas Law (PV = nRT)

Folks,

It's been a while since I've done calculations like this so I was wondering if someone can help me calculate the volume of a gas at a specific temperature as compared to its liquid volume when measured below its boiling point. I can't seem to find a phase diagram for this material, is there a way to calculate it?

Assume that the gas is ideal, and use the ideal gas law ##PV = N k_\mathrm{B} T## (or ##PV = n R T##) to find the volume. To know ##N## (##n##), you can use the volume of the liquid and its density.
