SUMMARY

The discussion focuses on calculating the pressure inside a sealed 5ml container containing 1ml of water and air at temperatures of 20°C, 80°C, and 120°C. The key concepts involved are vapor pressure and the ideal gas law. Participants emphasize the importance of showing preliminary work to facilitate effective problem-solving. The discussion highlights the necessity of understanding both vapor pressure at varying temperatures and the application of the ideal gas law to derive accurate pressure calculations.

PREREQUISITES
  • Understanding of vapor pressure concepts
  • Familiarity with the ideal gas law (PV=nRT)
  • Basic knowledge of thermodynamics
  • Ability to perform calculations involving temperature conversions
NEXT STEPS
  • Research the vapor pressure of water at 20°C, 80°C, and 120°C
  • Learn how to apply the ideal gas law to mixed gas systems
  • Explore the relationship between temperature and pressure in thermodynamic systems
  • Investigate how to calculate partial pressures in a gas mixture
USEFUL FOR

This discussion is beneficial for students and professionals in chemistry, physics, and engineering fields, particularly those involved in thermodynamics, fluid mechanics, or anyone needing to understand pressure calculations in sealed systems.

Hi

I am trying to calculate the pressure in a vessel of 5ml that contains 1ml water while the rest can be considered as air. I would like to know the pressure at temperatures of 20C, 80C and 120C


I have a feeling its something to do with vapour pressure, and the ideal gas law but can't seem to work it out

Thanks in advance

You should show a little more of the work you already have done. Please follow the template.
 
PF isn't a Q&A website, we should not answer any question without knowing the work you've done or at least your approach into solving the problem ., What do you think the answer is, How can similar problems can be solved ?
