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.
What else can I help you with?
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.
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.
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.
How do you keep ice cubes cold with natural materials?
put them in cold water
How many sugar cubes can be dissolved in cold water?
The exact number of sugar cubes that can be dissolved in cold water depends on the size of the sugar cubes and the volume of water, but generally speaking, you can dissolve 1 sugar cube per 1 ounce of cold water. Keep in mind that the solubility of sugar decreases as the water temperature decreases.
Do sugar cubes dissolve faster in hot water or cold water?
Hot water
What is inside reusable ice cubes?
Reusable ice cubes are typically filled with distilled water or a non-toxic gel (such as polyethylene glycol) that can freeze and keep drinks cold without diluting them as traditional ice cubes would. Some reusable ice cubes are also filled with a non-toxic gel that can retain cold temperatures longer than water.
Why does ice cubes melt faster in hot water than in cold water?
because atoms in hot water vibrate faster, and cold water vibrates slower, hence movement generates heat, heat speeds up the ice cube's atoms, as the ice cube's atoms speed up it begins to expand, spread out it's mass and melt.
Do sugar cubes dissolve better in a hot place?
They will dissolve much quicker in warm or hot water than in cold water.
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.
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 does water became cold when you add some ice cubes to it?
Adding ice cubes to water causes the ice cubes to melt due to the higher temperature of the water transferring heat to the ice. This process requires energy in the form of heat, which is taken from the surrounding water, resulting in a decrease in temperature and making the water colder.
Does using hot water instead of cold water make clear ice?
Yes, using hot water instead of cold water can make clearer ice because it contains fewer impurities that can cause cloudiness in the ice.
