As a chemical engineer with years of experience in the field, I can provide an in-depth explanation for why molten salt explodes when it comes into contact with water. This phenomenon is a result of the extreme temperature difference between the molten salt and the water, as well as the rapid chemical and physical reactions that occur upon contact.
Molten salt, which is essentially salt that has been heated to a high temperature and is in a liquid state, is extremely reactive. When it encounters water, which is at a much lower temperature, the temperature difference leads to a rapid transfer of heat from the molten salt to the water. This heat transfer is so rapid that it causes the water to instantly boil and turn into steam.
The process begins with the dissolution of the molten salt in the water. Salt, when dissolved in water, absorbs heat from the water. This is known as an endothermic process. However, in the case of molten salt, the heat from the salt is so intense that it overwhelms the endothermic nature of the dissolution process. Instead of the salt absorbing heat, it imparts its heat to the water, causing it to heat up rapidly.
As the water heats up, it reaches its boiling point and starts to turn into steam. This transition from liquid water to steam is accompanied by a significant increase in volume. The steam bubbles form within the water and expand rapidly. If the molten salt is poured into a container of water, these expanding steam bubbles can cause a violent reaction, leading to an explosion.
The explosion is not due to a chemical reaction between the salt and water, but rather the physical properties of water under extreme heat. Water has a high specific heat capacity, which means it can absorb a lot of heat before it starts to boil. When it does boil, the rapid expansion of water into steam can be explosive, especially if it is contained in a small space.
Another factor contributing to the explosion is the Leidenfrost effect. This is a physical phenomenon where a liquid, in contact with a surface significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly. When molten salt hits water, the Leidenfrost effect can cause a delay in the boiling process, but once it starts, it happens very quickly and violently.
It's important to note that the safety precautions must be taken when handling molten salt. The potential for an explosive reaction with water is significant, and it can lead to serious injuries or damage. Protective gear, proper containment, and controlled environments are necessary to prevent such incidents.
In summary, the explosion that occurs when molten salt hits water is a result of the extreme heat of the molten salt causing the water to boil rapidly and turn into steam. The rapid expansion of steam, combined with the physical properties of water and the Leidenfrost effect, can lead to a violent explosion.

The salt itself doesn't explode, the molten salt is so hot that the water instantly boils to steam. As the water contacts the very hot molten salt it dissolves rapidly, transfering its heat to the water much faster than would happen if the salt did not dissolve.
