Question

Can the first law of thermodynamics be violated?

Answer 1

Thermodynamics is a discipline of physics concerned with the interactions of heat and other types of energy. It explains how thermal energy is transferred into and out of other forms of energy, as well as how it influences matter. The four laws of thermodynamics express the core concepts of the subject.

Complete step by step solution:
Because the total energy of the system is constant, the first law of thermodynamics cannot be broken, and the law is known to apply to all known physical and chemical systems.
Explanation:
Heat is a kind of energy, according to the First Law of Thermodynamics, and thermodynamic processes are therefore subject to the concept of energy conservation. Heat energy cannot be created or destroyed in this way. It can, however, be moved from one spot to another and changed into and out of different types of energy.
As a result of Noether's theorem, we now know that the first law of thermodynamics follows. The conservation of energy law must apply as long as time exhibits translational symmetry.
It doesn't, according to astronomers, on very large scales. The big bang comes to mind as an example of a violation, but so does the current epoch's accelerated expansion. However, those same astronomers go on to say that spacetime is Euclidean and flat at medium to small sizes (anything smaller than a huge cluster of galaxies).
So, no, time on our planet (in our solar system, throughout the Milky Way) exhibits translational symmetry (perform your physics experiment one minute later than you intended, or one minute earlier, and the findings would be the same), so the first law of thermodynamics must inevitably apply.

Note: The first law expresses the notion of energy conservation. The fulfillment of the first law does not guarantee that the process will take place.
Examples:
A cup of hot coffee left in a cooler room will cool down eventually. The opposite of this process does not occur: coffee does not become hotter as a result of heat transfer from a cooler room.
Consider how an electric current passing through an electric resistor can heat a room. The transfer of heat from one room to another does not result in the generation of electrical energy through the wire.
Consider a paddle-wheel system that is powered by mass fall. The internal energy of the fluid increases as mass potential energy falls. The reverse procedure does not occur, even though it would not violate the first law.
Potential energy is turned into K.E. as water flows downhill. In nature, this process does not reverse itself.
