Anti-matter and thermodynamics

AI Thread Summary
When a particle of matter collides with its corresponding antimatter, they annihilate each other, but this process does not violate the laws of thermodynamics. The energy from the annihilation is transformed rather than destroyed, maintaining the overall energy balance in the universe. The creation and destruction of matter-antimatter pairs are consistent with these laws, as they involve energy conversion rather than loss. This means that while matter is destroyed, the energy remains conserved. Understanding this principle clarifies why such interactions do not contradict thermodynamic laws.

if a particle of matter and anit-matter collide they are annihilated.
Does this violate the laws of thermodynamics? Got to thinking about it while reading a brief history of the universe.

In what way would it violate the laws of thermodynamics?

Because it's matter being destroyed. I'm actually curious, too, if anyone cares to answer: why doesn't the creation/destruction of matter/antimatter pairs violate the laws of thermodynamics? I guess it might not change the overall amount of energy that exists...still, I don't really get what the deal is with those new matter/antimatter pairs.

Welcome to PF. This is quite an old thread, posting on threads that no one has commented on for years isn't really desirable.

But to answer your question there is no violation because no energy is being created or destroyed, merely changed from one form to another.
 
Thread 'Thermo Hydrodynamic Effect'

Thread 'Thermo Hydrodynamic Effect'

Vídeo: The footage was filmed in real time. The rotor takes advantage of the thermal agitation of the water. The agitation is uniform, so the resultant is zero. When the aluminum cylinders containing frozen water are immersed in the water, about 30% of their surface is in contact with the water, and the rest is thermally insulated by styrofoam. This creates an imbalance in the agitation: the cold side of the water "shrinks," so that the hot side pushes the cylinders toward the cold...
