Why are ice cubes made with hot water clearer then those made with cold water?

The difference between clear ice made by freezing previously-heated water and cloudy ice made from ordinary cold tap water is the presence of trapped air bubbles in the cloudy ice. The trapped air comes from gases that were dissolved in the cold water, but which come out of solution during freezing. When water is boiled, or raised in temperature, the solubility of gas is reduced and it comes out of solution, so that when that previously heated water is frozen there are no bubbles formed and the ice is clear.

Why the gases are more soluble in cold water than they are in hot water?
gas is more soluble in cold water. In hot water, the molecules are farther apart, leaving room for gas to escape. That's why it's LESS soluble, and why hot water makes clearer ice cubes. Cold water molecules are close together, trapping in the gas and dissolving it. We keep pop in the freezer so the carbonation will last longer.
What are facts about melting ice cubes?
*melt because of heat *melt better when run under cold water *apparently salt melts it better google some more
Why do ice cubes stick together in the freezer?
Answering the question and the question in the details below:Ice cubes stick together because the surface of ice is liquid-like and when the ice cubes touch, the surfaces freeze together. For more background, please view the answer to "Why is ice slippery?"The following answer gives some scientific details pertaining to ice:Water freezes at 0 degrees celsius, but the ice that comes out of your freezer is much colder.From the moment you put ice into water, the water gets colder and the ice gets warmer until there is one uniform temperature and all ice has turned to water. You can imagine how if the ice were cold enough, it could freeze all the water.Two cubes of ice at say -10C would easily freeze a thin layer of cold water surrounding them before they get down to the temperature at which they begin to melt.BUT I have noticed that often cubes that are half-melted will still stick together. How can this be? If it has been shrinking, the outer layer should be in the process of melting and therefore not cold enough to freeze its surroundings. I do not know the explanation for this. Perhaps I wasn't watching closely enough. Maybe they froze together when they were larger and for some reason the connections don't melt as fast as the other parts of the ice. More experimentation needed.
Beverage glass is filled to the brim with ice cold water 0C and ice cubes Some of the ice cubes are floating above the water level When the ice melts the water in the glass will?
When all the ice melts (it will take a while with the water at 0C), the water level in the glass will not be in any danger of overflowing the container because water is one of those rare liquids that expands when it freezes. (This is why a closed glass container of water put into a freezer will break.) This means that it contracts as it melts.The specific water level of the glass will depend on how much ice was floating above the water level, but it won't be in any danger of overflowing. As a matter of fact, the water level will actually be lower than the rim of the glass.
Are molecules in hot water different then molecules in cold water?
If you have the same volume of both then there are in cold water more molecules.
Why don't ice cubes melt faster in cold water?
Ice cubes don't faster in cold water because the temparature of cold water is low, ice cubes melt faster in high temparature.
Is Hot or cold water better for making ice cubes?
Science is AMAZING!Well, when you put it in the freezer, hot water becomes cold water before it becomes ice. So, cold water makes ice cubes FASTER, but there is otherwise no difference in the quality of said cubes. Forgot to make those ice cubes?Hot water when it hits the freezer makes ice faster. Generally every day for a week I make two trays of small ice cubes (with hot water) and then throw them into separate Glad bags and stick in the freezer. This way you don't have to buy a bag of ice at the last minute and always have plenty on hand for unexpected guests. ANSWER:Warm or hot water will make clearer cubes than cool water. If you want clear cubes, use warm water. cool water will have air bubbles in them. UPDATE:Using warm or hot water causes the icecubes to freeze slower, so in theory, it allows the air to leave the water more and form more solid cubes. In fact, if you boil water and get as much of the oxygen out of the water as possible, you are able to make very 'clear' ice cubes with very little imperfections in them (like on the soda commercials with the ice cubes that are perfectly crystal-clear). CORRECT UPDATEYes, warmer water freezes before cold water. It is called the Mpemba Effect. And the reason the ice cube in soda commercials are perfectly clear is because they're made of glass.
How do you keep ice cubes cold with natural materials?
put them in cold water
Do sugar cubes dissolve faster in hot water or cold water?
Hot water
What does the outside of the glass with ice cubes feel like?
It feels like ice , and glass like . · The glass filled with cold water and ice cubes felt cold on the outside as well.
Why do ice cubes stick together at times?
A cold glass of water sometimes causes water vapour from the surrounding air to condense onto the surface of the glass. The same thing happens with ice cubes, but instead the water droplets condensing on the surface, they will instantly freeze and 'weld' ice cubes together. They also can stick together if put into a drink, where again, the water in the drink near the surface of the ice cube may get cold enough to freeze and cause the ice cubes to fuse together.
Why does dew form on a can with warm water and ice cubes in it?
Because of condensation formed by the cold of the ice and metal meeting with the warmth of the water.
Do sugar cubes dissolve better in a hot place?
They will dissolve much quicker in warm or hot water than in cold water.
Will hot water freeze into ice cubes faster than cold water in your freezerSupport your answer with reasons?
No, it won't. It takes more energy for the freezer to reduce the temperature of the hot water to the freezing point - than it does with cold water.
Why does water became cold when you add some ice cubes to it?
The ice cubes appear clearer after freezing since warm water contains fewer dissolved gases than cool water. Some people do it because they think it freezes faster. This is only true in certain cases, though; specifically, if the air in the freezer is saturated with water vapor (which is fairly likely) warm water will freeze more slowly than cool water.
Will ice cubes melt faster in hot or cold water and what is the scientific reason for it?
Ice cubes melt faster in hot water. Hot water has more heat energy to overcome the forces of attraction between water molecules in ice. Go look up the kinetic particle theory.
Do sugar cubes dissolve faster crushed or whole in hot or cold?
I never heard of crushed water. Crushed ice (which sugar cubes don't dissolve in at all), but not crushed water. Let's see here: sugar dissolves faster in hot water than cold. And crushed sugar cubes, because the sugar has more surface area, dissolve faster than cold ones.
