An absolute zero, a sample of an ideal gas would zero volume. Why if not true the actual gas at absolute zero.

I'm not 100% sure what you are asking, but I can tell you that everything breaks down at absolute zero, and equations like PV=nRT just wouldn't work anymore, assuming you could actually do it, which we can't.An absolute zero, a sample of an ideal gas would zero volume. Why if not true the actual gas at absolute zero.
you can not reach absolute zero





you can get with in a billionth of a degree but never get there completelyAn absolute zero, a sample of an ideal gas would zero volume. Why if not true the actual gas at absolute zero.
it cant be absolute zero....where wil all the stuffs inside the atoms go...they will need some space to stay na?
That is not a question, or even a sentence.





The Physical Laws as we know them would not work at Absolute Zero, certain calculations will either result in zero, of infinity, or divide by zero errors.





Second, of course, no gas would still be a gas at that temperature, it would have long since become a solid. So again, the Gas Laws don't apply.





Third, as pointed out, we can't actually achieve absolute zero, there will always be residual energy, so the point is moot anyway.
First off, no actual gas is an ideal gas. An ideal gas is made up of particles taking up zero volume and having no interactions between particles. An actual gas is made up of molecules that have a nonzero volume and also have intermolecular interactions. Hence an actual gas cannot have zero volume at absolute zero. This is a purely classical argument and doesn't include quantum effects.. There will be quantum fluctuations that would also help to keep the gas from having zero volume.
