We can always be certain that fire creates heat that causes heat when water is present. But why is the fire hot and the water wet? I doubt that everyone here is considering this.
The article below contains the response to the aforementioned, seemingly ridiculous query.
1. How did the water get wet?
Here is the response to the query “why is the water wet” that was placed on the website of the University of California, Santa Barbara (UCSB).
Water is a liquid that may saturate other solid objects, but it can not saturate itself.
The capacity of a liquid to cling to a solid surface is known as moisture. The presence of fluids on a surface indicates that it is moist.
The balance between the forces of adhesion (which occurs when two dissimilar things stick together) and cohesion (which occurs when two similar things stay together) determines whether an object is wet or dry.
The attractive force in a liquid known as binding force is what causes the molecules in the liquid to adhere to one another. Surface tension of the item and the binding force are connected. If the binding force is high, the liquid’s molecules are packed closely together, preventing them from spreading out across an object’s surface. The attraction between a material’s surface and a liquid is the adhesive force. The liquid will spread to the surface if there is a significant adhesive force.
Therefore, how moist the object’s surface is depends on how these two forces interact.
- If the adhesive force (liquid-solid) is stronger than the bonding force (liquid-liquid), the liquid will spread out to make the most contact with the surface.
- The material won’t become wet (dry) if the adhesive force (liquid-solid) is larger than the bonding force (liquid-liquid). The liquid has a propensity to form a spherical drop, minimising physical touch.
Water really has quite a strong bonding force because of hydrogen bonds. Water’s capacity to moisten the surface is therefore inferior to that of other liquids, such as acetone or alcohol. Even certain liquids, like mercury, may be used without wetting the substance.
When detergent is applied, the water’s binding force decreases, improving its wetting capacity.
The aforementioned explains why it is likewise a liquid, but that liquids like water, cooking oil, milk, etc. have varied amounts of wetness.
2. The fire is hot, why?
The formation and breaking of chemical bonds during combustion, claims Thoght.co, releases heat energy. Fuel and oxygen are converted during combustion into carbon dioxide and water. Energy is needed to dissolve the bonds in the fuel and between the oxygen atoms in order for the reaction to happen. More energy is released when atoms combine to make carbon dioxide and water.
Heat and light are both energy that is emitted and exist as a flame. Both flames and embers shine from ionised gases and material that is hot enough to produce incandescent light.
In other words, the fuel’s energy is quickly released, which causes the fire to heat up. The energy released is far greater than what is required to start a chemical reaction.
