What Are The Exceptions The 'Laws' Of Thermodynamics?

Happy Thanksgiving!!

I have thought along those lines for a couple of decades now. It seems to me the collision of two billiard balls is not a thermodynamic event. A dynamic event, yes, but not a thermodynamic one.

The equation for momentum, mv, contains to term for temperature. So in general energy of motion is independent of heat.

It seems to me the generalization you question is too broad and has not been examined with sufficient care. I am working on a device based on the alternate premise.

Feel free to contact me on the side if you wish.

I also wonder whether there is such a thing as a closed system, given that a perfect insulator does not exist.

The zeroth law is really a definition--or can be proven from the definitions--so there aren't going to be exceptions to it unless we completely reformulate thermodynamics.

There are no known exceptions to the first law

The second law is statistical in nature. So in a microscopic system, it is conceivable that a system could move from a less ordered state to a more ordered one. If you have 10 particles in a box, you could find them all on one side. Only when you have larger numbers does the law become hard and fast. All the air mollecules in the room will not migrate to one side. You can't build an engine that moves heat from a cold reservoir to a hot one without doing work.

The third law doesn't come up too often--I had to look it up to even remember what it was.

------if you're trying to suggest that mass/energy conversions violate the first law, you're a century out of date. It is understood that energy includes the energy a particle has at rest--its mass.

If you are so sure that there are exceptions then prove it and you'll win the Nobel Prize. I am open minded to any evidence you can give. I don't consider the known laws of physics as a religion, I know they can change. So far I haven't seen any good evidence that there were are exceptions. If you have then present it. Calling someone brain dead because they don't believe something of which there is no evidence isn't a good scientific argument.

I was going to argue the same point as Bekki on the second law, she's already done it though, and it doesn't need saying again. I don't know of any exceptions, if you do, I suggest you prove them and present them for us to look at, then who knows, if you can prove them to be wrong, or indeed find exceptions, you may even win the nobel prize for Physics! Until that point, I suggest you don't label people as "brain dead" :o)

Why are you wasting time here? Go make a zillion dollars!
