SUMMARY

The discussion revolves around a thermodynamics problem involving a 1L container sealed at 20°C and 1 atm, which is then placed in boiling water. The key equation used is the Ideal Gas Law, PV = nRT, to determine the number of moles of air that escaped upon opening the container after thermal equilibrium. The critical factors are the initial conditions of temperature and pressure, and the final conditions after heating, which dictate the amount of air that can be held in the container at boiling temperature.

PREREQUISITES
  • Understanding of the Ideal Gas Law (PV = nRT)
  • Basic knowledge of thermodynamics and thermal equilibrium
  • Familiarity with concepts of pressure, volume, and temperature
  • Ability to perform calculations involving moles of gas
NEXT STEPS
  • Learn how to apply the Ideal Gas Law to different scenarios
  • Study the concept of thermal equilibrium in thermodynamics
  • Explore the relationship between temperature and gas volume
  • Investigate the effects of pressure changes on gas behavior
USEFUL FOR

Students studying chemistry or physics, particularly those focusing on thermodynamics and gas laws, as well as educators looking for practical examples of gas behavior under varying conditions.

A 1L container is open to the air. The container is then sealed and
placed in a bath of boiling water.

After reaching thermal equilibrium, the container is opened. How many moles of air escaped?

Hi curiousM! Welcome to PF! :smile:

This is PV = RT question.

Just ask yourself … which of P V and T are given, for the important time?

The important time in this case is immediately after the container is opened. How much air at the temperature of boiling water can the container hold?

And how much was actually inside?

So how much must escape? :smile:
 
Thanks fot the help.
