1g of salt dissolved in 1g of water, why is the total mass not 2g?

Isn't this a very simple 1 + 1 equals 2 problem?

However, that is not the case. Such a simple question holds a colossal mystery, and possibly even the most fundamental mystery of the universe, related to a core theory proposed by Einstein: mass is energy.

It will also explain to you why one gram of salt is dissolved in one gram of water, and the final total weight is not 2 grams.

To analyze this simple problem, we have to introduce some concepts: the law of conservation of mass (i.e. when any matter in the universe reacts, the total mass before the reaction is equal to the total mass post-reaction), if there is a decrease in total weight, this means something is escaping in an invisible way. If there is an increase in total weight, that means something is absorbing something else.

When one gram of salt dissolves in one gram of water, two cases can occur:

1. 1. One amount of salt + one amount of water = 2 amount of salt water
2. 2. One catty (an ancient unit of mass) of salt + one catty of water = n catty of salt water + △ E (where △ E is the change in energy or change in matter)

If formula 1 is established, the conditions that need to be met are very severe, and 2 catty of brine must be obtained in a closed and adiabatic environment. The phenomenon in equation 2 normally occurs only in experiments.

Combined with the mass gain effect in Einstein's special theory of relativity, when a molecule is moving violently, the kinetic energy of the molecule is greater, its relativistic mass is greater, the more strongly the molecule is moving, the more kinetic energy is. larger and relative. Equal mass will also lead to higher temperature In other words, Einstein's special theory of relativity emphasizes that the nature of mass and energy are the same.

Since the nature of mass and energy are the same, when there are other interference phenomena during the dissolution of salt in water, the final total mass will not be equal to 2 cathodes (a physical electrode that where the current leaves a polarized electrical device). For example, if the room temperature changes by 1°C, the change in temperature will also affect the quality.

Of course, in real life we ​​don't care about those advanced laws and the like, we just assume that the result is Equation 1. But scientists are working on nitpicking (description). the act of paying too much attention to detail), and any subtle influence can affect the accuracy of the experiment, so it is said that from the simple question of a gram of dissolved salt dissolved in a gram of water, it can also lead to the most fundamental mystery of the universe.

The simple question of whether 1 + 1 equals 2 when explained by Einstein's mass-energy equation E/m = c^2 is so.
