Compare Water

Question: Compare the time taken for a pendulum swinging in water and a pendulum that is swinging in air? What i mean is if a pendulum is made to swing in water, compare the time taken for this pendulum to come to a complete stop with the time taken by a pendulum swinging in air. Explain the difference. Thank you.

Answer: dunno

Question: How does the density of a glass of water compare to a pool of water? how does the density of a glass of water compare to a pool of water?

Answer: The mean density of the pool is higher by a tiny bit. Water is not perfectly incompressible, the pressure of the water body will make the density near the ground a bit higher than that near the level.

Question: How does the mass of water compare to the mass of ice? When ice melts, the volume of water is smaller than that of the ice. How does the mass of the water compare to the mass of the ice? ... I'm not talking about densities though..

Answer: MASS is the same for both water and ice, 18 grams/mol. The DENSITIES are not the same and the VOLUMES are not the same. Density is mass per unit volume. The density of ice is LESS than the density of water and that is why ice floats.

Question: When ice melts, how does the liquid water compare to the ice? When ice melts, how does the liquid water compare to the ice? -The liquid has a greater mass and greater volume than the ice. -The liquid has less mass and less volume than the ice. -The liquid has less mass but the same volume as the ice. - The liquid has the same mass but less volume than the ice.

Answer: Mass will remain the same, but volume will reduce by about 8%. Water is a unique compound that expands when it freezes rather than contracts.

Question: How do diet drinks compare to water when on a diet? How do drinks like diet iced tea or the slenderize versions of "Fuze" compare to water when watching what you eat? These drinks have 0g of Fat, 0-5 Calories, no sugar, and no high fructose corn syrup. They seem like they would be just fine to drink as long as you drink plenty of water in addition to them. What do you say? Per user request the carb count: Fuze Slenderize: 1g Diet Iced Tea: 0g

Answer: In relation to water and these drinks, you may get a bit of caffeine in there (which is perfectly healthy and needed) and well frankly some flavor. Honestly, with the miniscule amount of... well anything in those drinks, you have nothing to worry about. No diet should ever see those drinks in the banned list, and I personally think you would be better off with some variety in your drinks, not just water. Good luck on your diet, just remember to not sweat the big stuff, but try to sweat a little bit! (on the treadmill anyways) ^-^

Question: Why do you think the local lake water compare as it did? Why do you think the local lake water compare as it did?

Answer: Your questions doesn't make sense but I'll give it a shot. Lake form from runoff from rain fall which gather in low lying areas. Also by a glacier that was once there and has since melted.

Question: How does the frequency of a vibration of a small object floating in water compare to the number of waves....? How does the frequency of a vibration of a small object floating in water compare to the number of waves passing it each second?

Answer: They are the same.

Question: How do the hydrogen bonds between water molecules compare to the covalent bonds within water molecules? How do the hydrogen bonds between water molecules compare to the covalent bonds within water molecules? Hydrogen bonds are between two hydrogen atoms. Covalent bonds are between a hydrogen and an oxygen. The hydrogen bonds are more easily broken than the covalent bonds. The hydrogen and covalent bonds are both polar. The hydrogen and covalent bonds both involve electron sharing.

Answer: Hydrogen bonds are between one hydrogen atom which is delta + with a oxygen's lone pair on another water molecule which is delta - Don't get too confused here, I'm basically saying one is more electronegative than the other. Covalent bonds share electrons between the H2 and O2 atoms thus are much stronger than hydrogen bonds, which are much weaker intermolecularar forces. When you heat water you are actually breaking the H-bonds BETWEEN the molcules, it is extremly difficult to break the stronger covalent bonds within the atoms however.

Question: How do the freezing point and boiling point of ocean water compare to those of distilled water? 1)Ocean water freezes at a lower temperature and boils at a lower temperature. 2)Ocean water freezes at a lower temperature and boils at a higher temperature. 3)Ocean water freezes at a higher temperature and boils at a lower temperature. 4)Ocean water freezes at a higher temperature and boils at a higher temperature.

Answer: freezes at lower and boils at higher.

Question: How does water temperature compare to air temperature? I'm doing a science fair project and I need a little info on water/air temperatures and how they compare for my informational 2nd paragraph of the conclusion. I used three cups of water and put them in three different places -- freezer, fridge, and room. The temperatures changed. Can you help me? I'm sure there's no universal difference, but...some kind of thing would be nice. I'll keep researching. Thanks for reading! :D

Answer: The temperature of a cup of water will change until it matches the temperature of the surrounding air. Beyond that, I am not sure what you are asking.

Question: How does jogging in water compare to jogging on land, for fitness? Not the kind of water jogging where you jog in deep water, just jogging across a pool in chest deep water?

Answer: Water is 800 times denser (thicker) than air. Because of this, it takes more energy to move through it. If you were to jog through it while trying to keep the same pace as you would on land, you would get tired faster. You also would not be able to cover the same distance in the same amount of time in water versus land. As a scuba diver, and instructor (for http://www.visibilityunlimited.com) ,we are taught to streamline ourselves and our equipment to reduce the drag caused by the water. Which is the opposite for someone who is working out in water. People using water for fitness use things like webbed gloves http://www.love2splash.com/category/702775321/1/Fitness-Accessories.htm and fins http://www.love2splash.com/category/702771681/1/Swim-Fitness.htm to increase drag.

Question: How would the freezing and boiling points of distilled water and seawater compare? How would the freezing and boiling points of distilled water and seawater compare? A. Both the freezing and boiling points of seawater would be lower. B. Both the freezing and boiling points of seawater would be higher. C. The seawater freezing point would be lower and the seawater boiling point higher. D. The seawater freezing point would be higher and the seawater boiling point lower. Ethylene glycol is the active ingredient in most commercial automobile antifreeze. Why wouldn't sodium chloride be used in a similar way? A. Sodium chloride solute does not lower the freezing point of water. B. Sodium chloride does not dissolve in water. C. Sodium chloride lowers the freezing point of water but has other undesirable characteristics. D. Sodium chloride is a solid while ethylene glycol is a liquid. Thanks for your help with these!!

Answer: When we put electrolyte boiling point increase and freezing point decreases. So your answer is C. NaCl will deposit in cooling pipes of the vechile and will block water path. thats why its not used. Option C

Question: How does tempra paint compare to water color, to oil and how do these compare to acrylic? I'd like to know which paint is usually considered best for beginners and also what is the best surface to put water color on? I am also interested in painting on wood. What is the best kind of paint to use on scrap wood? Any advice is helpful but I mostly want a comparison between a bunch of mediums. Thank you!

Answer: Water color, tempera and acrylic paints are all water-based. So brushes can be rinsed in water. There are special papers created solely for water colors which you can find at an art supply store. Oil paints, as you might guess from their name, are oil-based, take far longer to dry than the water-based paints, are mixed with linseed oil, white spirit (turpentine is too dangerous; it can damage your liver!) or other compounds. Brushes are cleaned with white spirit. You can paint on wood with either oils or acrylics. Paper or canvas should first be prepared with several thin layers of gesso before applying paint. You can start with oils or acrylics. Either way you're going to be learning how to mix colors. I am working with both and I think (for now) I prefer oils. My daughter loves acrylics. Go figure! Water colors, however, are a whole other thing!

Question: How does bottled water compare to tap water? It seems like more and more people are drinking bottled water nowadays. Is it as safe as tap water and how is it regulated? There seems to be many brands with "natural spring water", are there really that many natural springs around? Won't they eventually get used up?

Answer: Most bottled waters try to give the impression of coming from a natural spring, but in reality there are few natural springs that have a high enough output to stock the shelves of stores around the country (or around the world). As a rule, most bottled waters are in fact tap water which has been through multiple filtrations, and they often have natural minerals added after filtration to provide a "spring-water" taste. The easiest way to tell is to look at the "Nutrition Facts" section on the bottle. If the water is anything BUT natural spring water, the bottler is required to note it as such.

Question: What makes good water? How does Melbourne water compare with those other world cities? Sorry if the question doesn't make sense, it is straight from my science discussion sheet.

Answer: "Good" water is water that is clear, clean, odorless. germ free, soft (easy to lather) and good tasting (being tasteless). I have no evidence but, to my knowledge, most of Melbourne has good water by a world standard.

Question: How does reclaimed water compare to drinking water? What are the contaminate counts.

Answer: There should be no difference if the reclaimed water is treated properly. However, this is a difficult task as reclaimed water could contain all kinds of different compounds depending on the source. For example; household water may contain detergents, surfactants, pesticides, food particles, associated microbes, feces, etc. Industrial water may contain all sorts of chemical depending on the industrial process. This is why reclaimed water is not usually used for potable purposes.
