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
Ten pounds of ice is equal to ten pounds of water, or ten pints by volume, which is 1 1/4 us gallons.
25 gallons of plain water weighs 208.625 pounds.
25 pounds of water.
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.

Strictly speaking, the volume of water will increase. For example, if you have a 200 gram chunk of ice floating in 1000 ml of water, the volume of the water itself is 1000 ml. When the ice melts, the volume of water will be 1200 ml. However, if you're asking whether the water level in the container will go up or down, the answer is "neither." The ice displaces an amount of water equal to the mass of the ice. When the ice melts, the mass does not chance, so the amount of the original water displaced by the melted ice does not change. Hence, the water level will remain the same.

10 pounds of water (molten ice) = 1 imperial gallon. (at standard atmospheric pressure and temperature).
four pounds
200 litters
That is approximately 10.5 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.
If 12,000 btuh = 1 ton cooling = 2000 pounds ice; then 12 btuh will melt 2 pounds of ice to water.
Ice has a density of 0.92 grams per milliter. This means that ten pounds of ice is equal to 4.93 liters. This is equal to 20.84 cups of liquid water.
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.
