SUMMARY

The discussion centers on the ideal gas law represented by the equation PV=nRT and its implications for gas behavior in varying volumes. Participants clarify that when the volume (V) of a gas changes, either pressure (P) or temperature (T) must also adjust to maintain the equation's validity. This relationship underscores the importance of understanding how gases behave under different conditions, reinforcing the interconnectedness of pressure, volume, and temperature in thermodynamics.

PREREQUISITES
  • Understanding of the ideal gas law (PV=nRT)
  • Basic knowledge of thermodynamic principles
  • Familiarity with pressure and temperature concepts
  • Concept of moles in chemistry
NEXT STEPS
  • Explore the derivation of the ideal gas law and its applications
  • Learn about real gas behavior and deviations from ideality
  • Study the relationship between pressure, volume, and temperature in isothermal and adiabatic processes
  • Investigate the impact of changing gas conditions on physical properties
USEFUL FOR

Students studying chemistry or physics, educators teaching thermodynamics, and anyone interested in the behavior of gases under varying conditions.

Homework Statement


I was studying about gases..and a thought struck me: we are taught that gases have no fixed volume. They occupy whole of volume of container in which they're placed.
so what are we trying to calculate by the equation PV=nRT . I mean at a particular P T and n,
place the gas in containers having different volumes.

hi babita! :smile:

you can't … if V is different, then one of the others must be different also (usually the pressure)

that's why the equation is important! :biggrin:
