How many pounds of ice equal one gallon of water?

Answer 1

That depends on the type material you are referring to. Also, these are two different types of measurements. One is volume the other is weight or mass. Please edit your question to include more context or details.

Answer 2

One Imperial gallon (old British System) of water weighs 10 pounds so 7 pounds of ice would be 7/10ths of a gallon.
One US gallon of water weighs 8.33 pounds so 7 pounds of ice would be 700/833 ds of a gallon.

Answer 3

One pint of water is equal to one pound of water. This is due to the fact that one fluid ounce (volume) is defines as one ounce (weight) of water. There is a helpful mnemonic for this, "A pint is a pound the world around". Therefore, ten pounds of water has a volume of ten pints.

One gallon is equal to eight pints. To figure out how many gallons is equal to 10 pints, we do a simple math problem.

(1g/8pt)=(xg/10pt)

This is a simple conversion formula. The first expression, (1g/8pt), expresses the conversion ratio of 1 gallon to 8 pints. The second expression, (xg/10pt), expresses the unknown ratio "how many gallons are 8 pints?"

10pt(1g/8pt)=10pt(xg/10pt)

Here we are multiplying both sides of our equation by 10pt to isolate our x variable. We want to eliminate the division by 10pt on the right side of the equation.

1g*(10pt/8pt)=xg*(10pt/10pt)

This is just rewriting the same equation as above using the associative property to clarify the step.

1g*(5/4)=xg

Here we simplify our new expression. On the right side of the equation, 10pt/10pt = 1, so those terms may be dropped from the equation. On the left side of the equation, 10pt/8pt simplifies to 5/4. You'll notice that we dropped our unit notation in this term. When performing operations on measures (numbers with units attached), we can treat their units as though they were variables. We square them if they are multiplied and drop them when they are divided and we only combine terms with the same units. This will preserve the relationships between measure we use in our equations.

(1g*(5/4)/1g)=xg/1g

Here we divide both sides of the equation by 1g. Normally, this would be an unnecessary step as dividing by 1 has no effect on the equation. However, I want to demonstrate that we can remove the unit "g" from this equation.

5/4=x

This is a simplification of the above equation. We have arrived at the solution 5/4=x, where x is the number of gallons of water equal to 10 pints. We could have also written:

5/4g=xg

and been just as correct since we are, in fact, looking for gallons in our answer. We now know that 5/4 gallons of water equals 10 pints of water. Because one pint of water weighs one pound, we also know that 5/4 gallons of water weighs ten pounds.

But wait! We wanted to know about 10 pounds of ice! As it happens, when matter changes states (like water freezing into ice); its volume changes, but its mass (and therefore weight) does not. Freezing ten pounds of water will yield 10 pounds of ice. We don't need to do any further conversions to arrive at our answer.

Answer 4

That depends on the type material you are referring to. Also, these are two different types of measurements. Gallons is a measure of volume but the other is weight or mass. Please edit your question to include more context or details.

Answer 5

The answer is 8.34. One gallon of water weighs 8.34 lbs. If you want one gallon of water when your ice melts, you need to have 8.34 lbs. of ice.

Answer 6

A pint of water is a pound & a quarter (20 Oz) therefore a gallon is 160 Oz (10 Lbs) 3 gallons is therefore 30 Lbs in weight. 30 Lbs of ice = 3 gallons of water.

Answer 7

1 gallon of water equals 8 pounds of ice...
