How about writing the relevant equation?

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

Nope, not quite (if P,V and T were always constant what would be the point of the equation...? :tongue2:). 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:
