One is the temperature of the water could be warmer
Secondly when an ice cube is in water, conduction takes place. The kinetic energy of the water particles more time.moves to the ice causing it to melt. When in air radiation or convection must take place which will take
No, it wouldn't. a sugar cube would melt a lot faster in a cup of Hot water. the hot water helps it desolve more evenly than cold water.
A cylinder shaped ice cube will melt faster because it has a greater surface area than the rectangle-shaped ice cube has. Cubes of ice with less surface area will melt slower. Ice that has very low surface area has more ice concealed inside than it does on the outside. Therefore, ice cubes that have more surface area will melt faster... I hope this will help you.. :) ..
Been answered already.For the same temperaure, the ice will melt faster in the medium that extracts most heat from it.Now, compare the heat conductivity of water and air - you've got your answer!Water, because the heat is carried away up to 4x faster because water molecules are more tighly packed than air. === === There are many variables to this question. What is the temperature of the water? What is the temp of the air? Is either one moving or flowing? Is the air below freezing? An ice cube melts because the ambient layer of air or water around it is changed rapidly. Styrofoam cups and coolers are designed to slow this down. If you take ice that has a fan blowing on it, it will melt faster because the air removes this layer surrounding it and replaces it with a warmer layer.well, technically ice is water, so if the water is liquid, it would melt faster there, however if the air is warm that will melt it quickly too.AnswerThe ice cube in cup that is by itself will melt slower. Ice water will have less kinetic energy, so ice cube in ice water will melt faster. Compared to the cup, the temperature surrounding the cup is much higher than ice water and so kinetic energy will be higher. Thus, causing the ice to melt faster in cup. Thie answer bears on the temperature in the ambient air. If it is -50 C in the room the ice in the cup will not melt. It will, however, evaporate eventually. I guess the ice cube in the ice water would freeze, too, so in that case it's moot. HmmmWater will have more contact with the ice cube and absorbs heat better and hence, will be able to transport or transfer its heat to the cooler ice cube quicker. Initially, both air and water contact surfaces are equal in size. However, just as soon as melting of ice begins, the meltwater " skin " produced reduces the contact surface area of the surrounding warmer air, insulating slightly and absorbing some of the heat itself. As the meltwater flows down and off the ice cube, it is carrying some of that absorbed heat away from the ice, slowing down the overall melting process in air. Interestingly, ice cubes floating in water, will have both air and water contact surfaces. If you could study a side view of the melting ice cube, you would see that the portion below the water surface melts faster ( becomes smaller in size). To compensate for this loss of below-surface mass of the ice cube, it sinks slightly. It appears the air is winning the race but this is not true. The faster heat transfer of the water medium is actually pulling the cube down. This would be clearly demonstrated if you set the cube up (with an onion bag supporting net ) such that it was supported from dropping down lower and lower into the water as it melted. Then you would see the below surface portion virtually disappear. As this happens the top-heavy portion will want to turn turtle to compensate for the disappearing bottom half of the cube.it melts faster in water because I tried it before the person who said that should put more notes down....
Because cold slows down the hydrogen and Oxygen atoms (H2O) in water, they become more compressed (frozen). Heat, or temps above 32 degrees, tend to excite these atoms causing them to move apart thus causing them to melt.It only melts IF the environment is above the freezing point...in Antarctica it might never melt.Ice cube melts because when the room is in its normal temperature that is bout 25 degrees it melts the ice and when the ice melts a few minutes later it evaporates
Hot water, salt can melt an ice cube as well but hot water raises the temperature in the ice cube causing it to go through a phase change referred to as melting thus turning it to a liquid more rapidly than salt could.
Yes.
Salt water will melt an ice cube faster than flour water. This is because salt lowers the freezing point of water, causing the ice to melt more quickly. Flour water does not lower the freezing point significantly, so it will melt ice at a slower rate.
The melting rate of an ice depends on the temperature of the surrounding. If the temperature is higher in the surrounding then the ice will melt at a faster rate and if the temperature is low then it will take more time to melt. The process of heat exchange is important whether it is air or water.
I believe ice cubes in apple juice will melt faster, since water is clear, and juice is red, juice will absorb more sunlight than water will, and therefore heats up faster.
The ice cube made of salt and water will melt faster than the one made of sugar and water, which in turn will melt faster than the one made from just water. Salt and sugar lower the freezing point of water, which causes the ice to melt faster.
Yes; because the rushing water will use (erosion) to wear it away faster than the temperature surrounding the ice cube in the air will
A frozen juice cube will likely melt faster than a frozen water cube due to the sugar content in the juice, which lowers its freezing point. The presence of sugar allows the juice cube to start melting at a lower temperature compared to a plain water cube.
A sea water ice cube would melt faster than a normal ice cube because sea water has a lower freezing point due to the presence of salt. This means that it would require less heat energy to melt the sea water ice cube compared to a normal ice cube.
a ice cube in alcohol would melt fastest because of the heating molecules contracting with the ice cube molecules
It's because THE TEMPERATURE of the water. The higher temperature the faster melts.
The ice cube would melt faster in water than in air. This is because water can transfer heat more efficiently due to its higher thermal conductivity, leading to a faster rate of heat transfer from the water to the ice cube, causing it to melt more quickly.
No, it wouldn't. a sugar cube would melt a lot faster in a cup of Hot water. the hot water helps it desolve more evenly than cold water.
