1 gallon of water equals 5 pounds so 21 pounds of ice would equal 4 gallaons and 1 quart of water.
The above answer is incorrect, please read the following:
The maximum density of water occurs at 39.16 °F (3.98 °C). When water is cooled down to its solid form, ice. It expands to occupy 9% greater volume in this solid state, which accounts for the fact of ice floating on liquid water.
Water at its maximum density at 39 °F (4° C), weighs 8.3454 lb/gal. (US, liquid).
So the answer to the question:
21 divided by 8.3454 = 2.5164
So 21lbs of ice = @ 2 1/2 gallons of water at 39º F
That would be close to 26 gallons of water. Water weighs 8.3 pounds per gallon. If you freeze 8.3 pounds of water, it makes a bit more than 1 gallon, but 220 pounds of ice should come out to pretty close to 26 gallons of water.
If 12,000 btuh = 1 ton cooling = 2000 pounds ice; then 12 btuh will melt 2 pounds of ice to water.
500 ml of ice cream weighs approximately 1.1 pounds or 17.6 ounces.
Since 1 gallon of water weighs approximately 8.34 pounds, a 5-gallon ice cube would weigh around 41.7 pounds, assuming it is made entirely of frozen water.
Ice is lighter than liquid water because the molecular structure of ice allows for more empty space between molecules, causing it to be less dense. This means that a given volume of ice will weigh less than an equal volume of liquid water, resulting in ice floating on top of water.
10 pounds of water (molten ice) = 1 imperial gallon. (at standard atmospheric pressure and temperature).
four pounds
It would take about 1.25 gallons of water to make 10 pounds of ice cubes, as each gallon of water weighs approximately 8.34 pounds.
That would be close to 26 gallons of water. Water weighs 8.3 pounds per gallon. If you freeze 8.3 pounds of water, it makes a bit more than 1 gallon, but 220 pounds of ice should come out to pretty close to 26 gallons of water.
100g of water is equal to 100g of ice in terms of weight, since they both have the same mass. However, the volume of the ice may be slightly larger due to the lower density of ice compared to water.
That is approximately 10.5 pounds
ice
A 1 kg bag of ice will be larger than 1 liter (ice expands), but when melted, will be 1 liter of water.
No, it is not true. 1500 lbs of ice, if melted with no evaporation occurring, would equal 1500 lbs of water. When you freeze a liquid, nothing is added or subtracted at a molecular level. Therefore, no weight change could occur.
Ten pounds (160 ounces) of ice melts into ten pounds (160 ounces) of water. The volume decreases when ice melts, but the weight does not change.

If 12,000 btuh = 1 ton cooling = 2000 pounds ice; then 12 btuh will melt 2 pounds of ice to water.
