Explain with physics why you can t break the mirror and reunite

Macroscopically, according to the entropy increase theorem generalized by the second law of thermodynamics, entropy is irreversible, that is, the entropy of any object is increasing. When the mirror is broken, the entropy increases from an ordered state to a disordered state, which means that it can never be reduced in entropy, so the broken mirror cannot be reunited.

Microscopically, the intermolecular forces affect the recircle of the broken mirror.

The magnitude of the intermolecular forces (including repulsion and gravity and their resultant force f) is related to the distance r between molecules.

1) When r = r (r is on the order of about 10 to the minus 10th meter), the repulsion force is equal to the gravitational force, f = 0, and the molecular force is in equilibrium. r is called the equilibrium position.

2) When rr, the repulsion force is less than the gravitational force, and the molecular force behaves as a gravitational force, which increases first and then decreases with the increase of r. When r is greater than the effective distance of the molecular force (also known as the effective radius of the molecular force, about 10 to the minus 9th power), the gravitational force quickly tends to zero, and the molecular force is negligible.

The distance between the two broken mirrors is much greater than r, and there is almost no gravitational force to reunite.

The distance between the molecules is too large, and the force is too small.

Because of the action of molecular repulsion.

None of the broken pieces can be illuminated independently.

The robot's questioning is improving.

1. The fact that it is difficult to circle the broken mirror shows that there is gravity between molecules and repulsion at the same time.

2. Physically speaking, because the repulsion force is much greater than the gravitational force at this time, it is impossible to break the mirror and recircle in the solid state.

3. However, the glass can be melted at high temperature, and when the gravitational force between the molecules is greater than the repulsive force, it can be combined together and recooled to achieve the effect of rerounding.

Principle: The intermolecular forces should be expressed, and the distance between the molecules should reach the molecular diameter of about 10 to the 10th power.

And put the broken mirror together. They are felt to the naked eye, but almost all of the molecules are very far apart, and the gravitational pull between the molecules is not strong enough to draw them together.

The phrase that a broken mirror cannot be reunited has a double meaning. The first meaning is what we usually call slang for the maintenance of relationships between people around them. The second meaning has to do with a chemical element.

This mysterious chemical element is called entropy. But this entropy does not refer to a specific substance, but to a kind of curvature of the chaos of matter in the universe.

Around 1877, Boltzmann proposed a statistical-physical explanation of entropy. He proved in a series of ** that the macroscopic physical properties of a system can be considered as the isoprobabilistic statistical mean of all possible microscopic states.

For example, consider the ideal gas inside a container. The microstate can be expressed in terms of the position and momentum of each gas atom.

All possible microstates must meet the following conditions: (i) the position of all particles is within the volume of the container; (ii) The sum of the kinetic energy of all atoms is equal to the total energy value of that gas.

It's like a broken mirror being reunited, and it's not that a broken mirror can't be put back together. They are usually re-bonded with adhesive tape or glue, but the gaps they create can never be removed and cannot be re-bonded perfectly. And the existence of this gap is the best proof of the entropy element.

This element is usually found in some chaotic things. For example, in the universe. The irregular movement of countless particles in the universe after the collision of atoms** or planets. The occurrence of this phenomenon is related to entropy.

The physical principle of the difficulty of reuniting after breaking the mirror is that there is repulsion between molecules.

Because matter is made up of molecules, under normal circumstances, the molecules that make up the substance have a balanced distance from each other, and when the mirror is broken, and then want to connect it, the cross-sectional spacing far exceeds the equilibrium distance, so it cannot be reunited.

Repulsion, which refers to the force of repulsion between objects, is the opposite of gravity. This force exists between objects with an isotropic charge and between isotropic poles. The gravitational force of the molecule is inversely proportional to the distance to the 6th power, and the force of the molecule is inversely proportional to the distance to the 12th power.

When the intermolecular distance is rr0, both the gravitational force and the repulsive force decrease with the increase of distance, but the repulsion force decreases faster, so the intermolecular force behaves as gravitational force.

However, it also decreases rapidly with increasing distance, and when the order of magnitude of molecular distance is greater than 10 -10 m, the intermolecular forces become very weak and negligible.

Interaction forces

The action of force is reciprocal. As long as one object exerts a force on another object, the object receiving the force will in turn certainly exert a force on the object applying the force. In a nutshell:

Different application points, equivalence, reverse, collinear. A pair of interacting forces must arise and disappear at the same time.

Fundamental force

Electromagnetic force

The electromagnetic force is the second strongest of the four fundamental forces and acts between all the charged particles such as electrons. The electromagnetic force acting between the atoms and molecules of the solid gives the solid its hardness, and this force also has magnetic and luminescent properties. The particle that carries the electromagnetic force is called a photon, and it is also the particle that produces light.

Strong nuclear force

The strong nuclear force is the strongest of the four fundamental forces. It exists inside the nucleus (nucleus) of an atom and binds the neutrons and positively charged protons inside the atom together (the protons often try to push each other away, and if there is no strong nuclear force, they will fly away from each other). Particles that carry a strong nuclear force are called gluons.

Weak nuclear force

The weak nuclear force is the second weakest of the four fundamental forces. It causes radioactive decay (rupture of the nucleus of an atom) known as decay. A radioactive atom is unstable because its nucleus holds too many neutrons, and when beta decay occurs, one neutron becomes a proton, releasing electrons (in this case called a particle).

The weak interaction is transmitted by W and Z particles.

There should be gravitational force between molecules, and the distance between them is very small, and the distance between glass fragments is too large, which will be much greater than the distance between molecules where gravity occurs. The answer can be obtained by judging the question by using the basic content of molecular kinetics theory, and it is necessary to be familiar with the content of molecular dismantling and infiltration ear motion theory: (1) Matter is composed of molecules; (2) the molecules of all objects are in a never-ending motion without regular travel and (3) there is gravitational and repulsive forces that interact with each other

Personally, I think that the reunion relationship is completely feasible and worth trying.

First of all, understanding human nature is the key to understanding the reunion of the broken mirror. Everyone makes mistakes, even in the most intimate relationships. Maybe it's because life is too stressful, or maybe it's because you're used to the other person's presence and you don't cherish it anymore.

However, people can learn how to apologize and forgive, which is key to maintaining a healthy relationship. When people recognise these mistakes, they may truly realize their love and thus strengthen their determination to repair broken relationships.

Secondly, trust is also an important factor that enables people to repair broken mirrors and reunite. Even if you love your partner, but if you can't trust them again, okay or then the relationship may fail. Therefore, people need to work to restore trust in each other and reconnect through honest and transparent communication.

When people trust each other, it is easier for them to change past mistakes and make better decisions.

Finally, time is also indispensable for the relationship of reunion after breaking the mirror. It takes time and patience to repair a damaged relationship, which can take months or years. In this process, both parties need to learn to tolerate, accept each other, and work hard to move on from past hurts.

But if both are genuinely in love with each other and are willing to put in the time and effort to repair their relationship, then the process is also promising.

In short, I think the reunion is worth trying and looking forward to. Of course, this requires both sides to have the sincerity and courage to face the mistakes and difficulties of the past. If both are willing to work hard to maintain their relationship, then it is entirely possible to come out of the shadows of the past or start a new life.

Dear, what do you think?

As the name suggests, the original broken items can be reassembled into a complete state. In the realm of relationships, this refers to the fact that lovers who have broken up in the past are able to get together again and start a new relationship.

Many people have different views on the feelings of reunion. Some people believe that once trust and respect are lost in love, there is no way to go back to the way things were. Others believe that true love can transcend all obstacles and rediscover each other even if they have been gone.

Personally, I am more optimistic about the relationship of reunion. First of all, the development of feelings is full of twists and turns, and no lover can go all the way without small contradictions or even big quarrels. If we choose to give up because of these problems, the frustration we encounter in a relationship will become even more helpless and hopeless.

On the contrary, if we can get back together after some ups and downs, I believe that such a relationship will be more resilient and powerful.

Secondly, humans are animals with emotional memories, and we will retain deep memories of the good things we have experienced. Even after a breakup, we still miss each other deep down. If the breakup between two people is not due to a diluted relationship or mutual malice, but simply because of some practical problems, then a reunion is a good option.

Of course, the reunion is not entirely risk-free. Coming back together means that two people have to face each other's shortcomings and problems again, and there is a need to communicate and compromise. If two people don't have the same personalities or are not mature enough when dealing with problems, they may move towards a breakup again.

Therefore, I believe that the reunion does not necessarily apply to all romances, but needs to be measured on a case-by-case basis. If two people have a deep emotional foundation and can communicate openly and compromise with each other, then I believe that such a relationship will be more resilient and long-lasting.
