does color affect the rate at which an ice cube melts?
357464
It can because a dark color will absorb more heat or radiation causing them to melt faster, say in a black glass vs. a clear one.

The melting point is the same as the freezing point, usually. The freezing/melting point is usually lowered to a lower temperature by impurities due to the impurities "messing up" the crystal lattice of the solid phase. The crystal lattice cannot form as easily with a lot of garbage present, so it requires a lower temperature to accomplish freezing. Likewise, the polluted crystal lattice will melt easier and thus it will melt at a lower temperature. This is why we put anti-freeze into our car radiators, to keep your engine block from cracking from the freezing of the coolant water during freezing weather. I hope this helps

the outside of the cubes melt the fastest while the inside are still froze.  What happens is the inside refreezes the melting outside therefor sticking together.  This will even happen while in ther freezer (if it is a self-defrosting kind)

The water around an iceberg or floe becomes colder than freezing (like putting ice cubes in a drink), but won't turn to ice since it is salty.  And waters in the polar regions are down near freezing to begin with.  When the berg gets sunlight some of the surface will melt off.  When the berg finally drifts to warmer waters, it will melt until it is gone.\n\nFor an example: Take a sink and fill it with water.  Put in some rock salts and stir until dissolved.  Now put in several trays' worth of ice cubes.  Stir.  Some of the cubes will melt since the tap water was not freezing, but eventually the sink water will get to a temperature below 32 degrees F or 0 degrees C without freezing solid.  At that point the coldness of the water keeps the remaining ice cubes frozen and the ice cubes keep the water at a below freezing temp.  Eventually it will melt cause there will be heat absorption into the system raising the water temperature, but it will take awhile.

The first question has been asked and answered so many times, it should be permanently barred. Go learn some elementary physics.\n\nAs for the second question, it depends on how you take the cubes out. If you twist the tray, which a lot of people do, you will crack the crystalline structure of the ice, because somne of the ice adheres to the tray walls. If you run warm water over the borrom of the tray, they will all come out whole - but not as cold, because the water will have added calories to their edges of the cubes, melting them a little.

It already has, or do you not read that all the worlds ice formations are melting at an alarming rate.  Usually when the ice melts in your freezer, it is getting to warm in there.

Crystal growth can occur at about any speed, but if you want a regular single crystal, the slower it grows the less likely are defects. Sudden growth leads to snowflake-like dendrition. Certain minerals like e.g. diamond require some time and extreme conditions to crystallize.\n\nWindows for IR purposes can be either defined minerals or glasses. While glasses are formed by undercooling melts, for some mixtures that might take longer.

It would slightly lower the melting point since the introduction of the food coloring molecules disrupts the hydrogen bonding network of H20 molecules

snow isn't really white its just the amount of light that is bounced back so when it melt it changes states of matter and becomes a liquid which bounces back light differently

If the water is already frozen and you remove more heat, all you will get is colder ice.  Otherwise, we need to know at what point is it at in the latent heat of fusion.

The ice would gain 124.3 kJ in moving from -10 °C to zero.\nThe water would lose 252.0 kJ in moving from +10°C to zero.The difference in the two energies is sufficient to melt 383 g of ice.\nSo the mixture will be at 0 °C and will consist of 6383 g of water and 5617 g of ice.

usually a bag of ice cubes should work and should not turn warm, though it may turn somewhat watery. but when that happens, just switch to another bag. That's what i do all the time and obviously don't do it a place where it can get hot. haha

Ice freezes and melts at 0 deg Celcius, ice water at about -18 degrees.\n\nWhen ice melts, it goes from ice at 0 deg to water at 0 deg. In the process, absorbs 80 calories of heat per gram of ice. This is known as heat of fusion.\n\nIf you have ice in water, all at 0 deg, there is an equilibrium formed where some of the ice is melting absorbing heat of fusion from the water, and some of the water is freezing giving heat back to the ice. \n\nWhen you add salt to the mixture, the freezing point of the water is depressed below 0, so the heat absorbed from water causes it to cool below 0 rather than being refrozen into ice.

I discussed this experiment with some of my colleagues and we think that the CO2 (carbon dioxide) causes a stirring effect which distributes the temperature more evenly in the soda. The ice cubes serve as nucleation sites for the bubbles (a place for bubbles to grow). As the bubbles grow and then release they cause the ice cubes to circulate in the liquid. This circulation causes the warmer layer below the ice to mix with the colder upper layer of soda and ice. Have you ever noticed that when you use a straw to drink a liquid that the liquid at at the bottom of the cup is warm and requires a stir to evenly distibute the cooling? The "still" beverages (water and tea have no bubbles) will have a cold layer on top next to the ice and a warmer layer on the bottom. This would cause the ice to melt slower.\n\nHere is an experiment to try. Allow some soda to get flat overnite, then try the experiment again.\n\nKeep in mind that temperature is the average kinetic energy of the particles in a substance, whereas heat is the total energy of all the particles. The air and water may have particles moving the same speeds, but the water has more heat because there are more particles. \n\nPicture it this way. The ice melts as fast moving particles slam into the slow moving ice particles. As in any collision, some of the energy is transferred to the ice particle, and with its new energy it can break out of the crystal and flow as a liquid water molecule. \n\nTo make the ice melt faster, you can use hotter (faster moving) particles to slam into it. This is why the ice melts faster on a hot day than a cold one. Alternatively, you can just use more collisions. The water is much more dense than the air, with many more particles per cubic millimeter. Thus even though the water molecules have the same kinetic energy as the air particles, there are many more of them hitting the ice each second, and the ice melts faster.

ice never melts when it is in an environment of 0C.  any environment above that temperature will eventally raise the temperature of the ice to its melting point...\n\nit is an inherent property of ice to melt at temperatures above 0C.\n\ndry ice is not ice.\nsteel is not ice.\nice is solid water which is only found at or below 0C (at atmospheric pressure).\n\nthis has to do with the gibbs free energy of the transformation \nH2O (solid) ----> H2O (liquid)

Good question!  You obviously know that glacial ice is not the same as frozen water in an ice cube tray in your freezer!  (glacial ice is compressed snow)  My initial response was that icebergs float, so yeah, it would float.  Then I thought that seawater is salty, which can cause more dense things to float and doesnt nescessarily provide a good proxy for a cup of drinking water.  Thennnnnn (you like following my train of thought here?) I remembered that icebergs calve into fresh water lakes, too and float.  So my long-winded non-quantitative answer is yes.  :)\n\nI have no idea if there is a difference in rate of melting, but my best guess is that it might take SLIGHTLY longer to melt.
