The density of water at 4 °C is 1 gram per milliliter (1 g/mL).
There are 236.588 mL in one cup.
So 1 cup of pure water weighs about 236.588 g (about 8.3454 ounces, avoirdupois)
This is true at 4°C (39.2 °F) where water is the densest (1000 kg/m3, and is pretty close at most other temperatures above freezing and below the boiling point of water. Water at room temperature is 998.2 kg/m3.
It depends how small it is crushed and how tightly it's packed. The smaller it's crushed and more tightly it's packed, the heavier it is as there is more ice and less space between the pieces of ice. In the most finely crushed and firmly packed volumes of the frozen stuff, the cubic foot of crushed ice will approach being a solid block. A cubic foot of water weighs about 62.4 pounds. A solid block of ice of the same volume weighs about 57.5 pounds. A cubic foot of "normal" crushed ice might weigh 35 to 45 pound range. And it could weigh more or less.
when water freezes it expands therefor the water takes little space to take of a larger area then when it is placed in water it will float because it is less dense OR The simple, easy explanation: Water is one of the only liquids that expands when it freezes. Because it puffs up bigger when it's solid ice, it weighs less than water. And anything that weighs less than water will float on water like ice.
Warm air and warm water. Cold air and cold water keep ice cooler longer.
Liquid water molecules have more kinetic energy and are moving more freely than ice molecules, which are in a more ordered and rigid structure. As a result, liquid water flows more easily compared to ice, which is more solid and less fluid.
when crystal structure of ice breaks, the liberated molecule become associated so strongly that they pack together more closely than in ice crystal itself. as a consequence ice becomes less denser than water and floats on it
It depends how much water and how much ice you hae. if you have 1 ice cube and 6 cups of water, the water will weigh more. But, if you have 10 ice cubes and 1/4 cup of water the ice will weigh more.
They are virtually the same
The fastest way to cool hot water is to place the cup in a bowl of ice water or use an ice bath. Stirring the water will also help distribute the heat more evenly and speed up the cooling process.
This is because you are not changing the mass of the water, there are still the same amount of molecules in the cup, although more energized they still occupy [relatively] the same amount of room. I say relatively, because the molecules are slightly more spaces, due to the energy obtained with heat.
Yes, that is correct. This is because the water molecules in liquid form are more densely packed compared to the same volume of ice, which has a more open structure due to the arrangement of molecules in a crystalline lattice.
A gallon of water weighs about 8.3 pounds. The answer is ice. Ice weighs around 12.45 pounds, which is 50% more than a gallon of water, but when it melts and its weight is reduced by 50%, it weighs around 6.225 pounds, which is less than a gallon of water.
Yes, crushed ice will melt faster in a cup of water than in a cup by itself. This is because the water is a higher temperature than the ice.
Water expands when it freezes, so the ice will be higher.
If you are asking if a cup filled with water and ice, when the ice melts, will the water overflow, then the answer is no. As the ice becomes water, then it loses its ability to displace the water that it was first displacing as it was ice. So in the end, the water level won't raise or fall as the ice melts, it just replaces the space it once filled with water, leaving you with a full cup of water.
A cup of water and a cup of ice would have the same volume and mass because they fill the cup to the same level. However, the cup of ice would have a lower density than the cup of water because ice is less dense than liquid water due to its expanded crystal structure.
Oh, dude, 1 cup of ice makes about 1/2 cup of water. It's like magic, but not really. Ice just takes up more space than water because of its solid form. So, if you melt that cup of ice, you'll end up with less water than you started with. Science, man.
