Equation of state for an ideal gas

Click For Summary

Homework Help Overview

The discussion revolves around the conditions necessary for the ideal gas law, represented by the equation PV = nRT, to be applicable. Participants are exploring the assumptions and requirements for a gas to be considered ideal.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the conditions under which the ideal gas law holds true, including the need for constant pressure, volume, and temperature. There is also discussion about the characteristics of an ideal gas, such as the behavior of particles and their interactions.

Discussion Status

Some participants have provided insights into the necessary conditions for the ideal gas law, while others are seeking clarification on specific assumptions. There is an ongoing exploration of the definitions and characteristics of ideal gases, with no explicit consensus reached yet.

Contextual Notes

Participants are referencing textbook definitions and external resources to support their understanding of the ideal gas law and its conditions. The discussion includes considerations of the nature of gas particles and their interactions.

How about writing the relevant equation?

And what is mentioned in one's textbook or course notes?
 
PV= nRT
What condition must the gas be in for this equation to hold true?

Nope, not quite (if P,V and T were always constant what would be the point of the equation...? :-p). When we say an ideal gas, what do we assume about the gas?
 
PV=nRT

condtion to be valid:

the gas has to be an ideal gas,

1.gas composed of seprate particles
2.particles behave as point masses
3.point of mass are far apart and do not exert any force


is this correct??

Sounds about right to me, but I would add ellastic collisions to that list. :approve:
