I had to completely delete the stuff that was here; it was too off the wall. Here's a key question that goes to the wording of the question in question. (I was going to rephrase the question, but I decided it would be better to ask, instead.) Should the question have read, "How much does a solid block of ice weigh if it is made from one gallon of pure, distilled water in a hermetically sealed container at or slightly below 32 degrees F"? Note the slight difference in wording that makes a significant difference to what is implied. In my reworded question, you start out with a gallon a water and then freeze it. In the original question, it looks like you END UP with a solid block of ice that occupies a one-gallon container. Since water expands when it freezes, you would have to start out with LESS than a gallon of liquid water in order to end up with an unbroken, one-gallon container of solid ice. Since the mass of water -- or anything else!! -- doesn't increase when it freezes, a gallon of liquid water weighs as much as a solid block of ice made from a gallon of liquid water. It WILL have greater volume, however, since ice is less dense than liquid water, and might distort or perhaps burst its container as it freezes. If my wording is correct, then the ice weighs as much as it would if it were in liquid form: 8.33 pounds. See the related question to the right for more discussion.
Distilled water, if it is truly distilled to purity, has a pH of 7. This means that the concentration of hydrogen ions dissociated from the water is 1x10-7 mol dm-3. Often, distilled water is impure, and is slightly more acidic (it has a slightly lower pH than seven).
pure water is slightly acidic because of dissolved carbon dioxide
tap water can be either slightly more acidic or slightly more basic than 7.0 on the pH scale. distilled water is approx. 7.0 a.k.a neutral
It can work slightly, but will not be as good.
65 degrees Fahrenheit is slightly below the lower range of what is considered room temperature. The range is around 68-79 degrees Fahrenheit.
water is a covakent molecule that dissociates slightly H2O <-> H+ (aq) +OH-
Distilled water has a pH between 5.6 and 7 i.e. it is slightly acidic. This is due to absorption of carbon dioxide from atmosphere to form carbonic acid
It is just slightly over 6 degrees Celsius
Slightly cooler than the human body temperature.
glycerin is distilled at reduced pressure because it has boiling point of 290 degree celsius under atmospheric pressure it slightly decomposes but under reduced pressure it distills unchanged
Glycerine is distilled over reduce pressure as at its boiling point 290 degree celsius under atmospheric pressure, it slightly decomposes, but under reduce pressure it distills unchanged.
In terms of human body temperature, it is slightly above normal.
The normal body temperature for a lion is 101 degrees Fahrenheit. This is slightly higher than a humans body temperature, which is 98.6 degrees Fahrenheit.
Heat it slightly in its original container... submerge it in a pan of warm, not hot water.
480 degrees Celsius or 864 degrees of Fahrenheit. It is the difference between a slightly cool day of 68 degrees Fahrenheit and turning to ash on Venus at 932 degrees Fahrenheit.
The normal body temperature for a lion is 101 degrees Fahrenheit. This is slightly higher than a humans body temperature which is 98.6 degrees Fahrenheit.
Distilled water would evaporate slightly faster, all conditions being equal, because dissolved minerals reduce the vapor pressure of tap water in accordance with the colligative properties of water.
No because they have different densities so the volume of the two combined will be slightly less.
Yes, grape juice is slightly acidic
Distilled water could be used in place of saline solution to upset a patient's homeostasis by having them ingest a fair amount of it. The human body has fluids that are slightly salty and have a pH of around 7.4. Distilled water should have a pH of 7.
35Â° Fahrenheit = 1.7Â° Celsius 35Â° C = 95Â° F 35Â° F is only slightly warmer than ice. 35Â° C is only slightly cooler than body-temperature. 35Â° F is colder.
Certainly. It is water and will freeze at the freezing point of 32 degrees F. Impurities in the water will slightly change the freezing point.
the theoretical ph of distilled water is 7.0, in practice, however, most distilled water will have a ph is slightly acidic (less than 7.0) due to the presence of carbon dioxide (co2) that is absorbed from the atmosphere dissolved carbon dioxide reacts slowly with water to give the bicarbonate and hydronium ions......

optimal temp: 59 deg. Fahrenheit. Warmer than a fridge, but slightly cool.
80.9 degrees Fahrenheit is slightly higher than 26.3 degrees Celsius
