Whats going on in this video with the water ?

In summary, the conversation discusses the effects of throwing hot water into the air at -45F and the possibility of evaporation and freezing into tiny ice crystals. It also mentions the difference in reactions between hot and cold water when put in a freezer. The conversation concludes with the idea that the reasons behind these effects are complex and involve multiple smaller factors.

ok so this guy throws up a cup of hot water at like 45 below zero F. And I am not sure what exactly is going on . Does the water first evaporate really fast and then freeze into tiny ice crystals. When its really cold outside the humidity is really low, so does stuff evaporate really quickly.

This isn't that hard of a question, I am just asking what will happen to hot water when i throw it in the air at -45F.

Hello cragar.Throwing the water breaks it into smaller drops and increases the rate of cooling.I think your answer is right.

So there is some evaporation, because it disperses very quickly. Thanks for responding by the way .

I would like to see the same thing with cold water to see if there is any difference.

If you put a cup of hot water and a cup of cold water in a freezer the cup with hot water will freeze first... (I don't remember why exactly) So there are some hard to guess effects that can happen.

heat=level of molecular activity

hot things react more with their environment

But they soon cool down to react just as much as the cold stuff would... And the cold stuff would already have a head start so it's not quite so simple. I think the reasons turned out to be fairly involved (multiple small effects added together).
 

FAQ: Whats going on in this video with the water ?

What is happening in this video with the water?

In this video, water is being poured into a glass container. As the water flows into the container, it creates ripples and bubbles on the surface.

What causes the ripples and bubbles in the water?

The ripples and bubbles in the water are caused by the force of the water being poured into the container. This creates disturbances on the surface of the water, resulting in the ripples and bubbles.

Why does the water appear to change color in some areas?

The water may appear to change color in some areas due to the refraction of light. As the water moves and ripples, it bends and reflects light differently, giving the illusion of different colors.

What other factors can affect the movement of water in this video?

The movement of the water in this video can also be affected by the shape and size of the container, the temperature of the water, and the speed and angle at which it is poured into the container.

What can we learn from observing the movement of water in this video?

By observing the movement of water in this video, we can learn about the properties of water, such as its ability to flow and form ripples and bubbles. We can also learn about the effects of external forces on the behavior of water.
