Why is there a difference between boiling water and cold water? How does the science explain it?

Because the temperature of the water is different, the effect on the bottle will be different, and the sound conveyed will be different. To explain it in a scientific way, the water temperature is different, so the surrounding air pressure will also have different flow rates, so the sound will be different.

Because the activity of water molecules in boiling water is particularly strong, the water in the liquid evaporates relatively quickly, while the activity of cold water molecules is relatively weak, and the volatilization of the liquid inside is relatively slow, so the sound is relatively crisp when it comes to cold water, and the sound is relatively thick when it comes to hot water.

Because the temperature of these two types is different, the sound and density of the collision with the ground air are completely different, and the sound is crisper if it is cold water. It's magical.

Boiling water has a relatively large heat and the thermal movement of water molecules is more intense.

After the water is boiled, the activity of the water molecules is greatly increased, and the attraction between the molecules is greatly weakened, at this time, not only the water on the surface of the liquid evaporates quickly, but also the water molecules inside the liquid also rush to vaporize and fly out, so the speed of escaping in all directions at the moment of falling to the ground will be faster than that of the water molecules of cold water. Therefore, this layer of elastic water vapor is always sandwiched around the boiling water, so the sound is not loud

When the water temperature is relatively low, the activity ability of the water molecules is weakened, the attraction between the molecules increases, the water molecules inside the liquid no longer vaporize, and the surrounding water vapor layer gradually disappears.

Let's take an analogy: a bag of sand is like a piece of wood that causes them to fall to the ground. Suppose that each grain of sand is understood as a molecule, then the density of sand is smaller than that of wood, and when it falls to the ground, it can escape in all directions, so the sound becomes smaller.

This has to do with hydrogen bonding in water. The temperature in hot water is high, the hydrogen bond is less, and the molecular polymerization and clumping phenomenon is weak. However, the cold water has a low temperature, a high hydrogen bond content, and a strong molecular polymerization phenomenon. It's like pebbles and sand falling to the ground at the same time, and the sound is definitely different.

Hot water has water vapor, and the molecular movement of hot water is more frequent than that of cold water.

First of all, the air in cold water dissolves in water and exists as a liquid, and when the cold water collides with the ground, the dissolved air cannot be turned into gas in advance to collide with the ground.

After the water is boiled, the activity ability of the water molecules is greatly increased, and the attraction between the molecules is greatly weakened, at this time, not only the water on the surface of the liquid evaporates quickly, but also the water molecules inside the liquid also rush to vaporize and fly out. Therefore, this layer of elastic water vapor is always sandwiched around the boiling water, so it makes a low "fluttering" sound.

When the water temperature gradually decreases, the activity ability of the water molecules decreases, the attraction between the molecules increases, the water molecules inside the liquid no longer vaporize, and the surrounding water vapor layer gradually disappears.

The carbon dioxide in the soda is dissolved under high pressure, and opening the cork is equivalent to a sudden reduction in the pressure on the liquid level.

Opening the cork is equivalent to a sudden reduction in the pressure at the liquid level.

When cold water collides with the ground, it is not possible for the dissolved air to turn into gas in advance to collide with the ground.

Because it's boiling water, it's already boiling point.

The air in cold water dissolves in the water and exists as a liquid.

When the boiling water temperature is very high, a reaction occurs.

After all, it's boiling water, and you always have to save face.

For some special reasons.

I think this kind of question still needs to be answered by future technology.

I guess that when boiling water is poured on the ground, some of it will quickly vaporize, quickly discharging the surrounding air, causing it to vibrate and produce a special frequency of sound.
