equation of state for an ideal gas

imy786

1. The problem statement, all variables and given/known data

What condition must the gas be in for this equation to hold true?

2. Relevant equations



3. The attempt at a solution

the gas has to be in constant pressure and volume and temperaute

How about writing the relevant equation?

And what is mentioned in one's textbook or course notes?

PV= nRT

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

What does one's text say about the Ideal Gas Law?

imy786

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.
