What is the effect of impurities on the melting point of ice and the boiling point of water?
The freezing point of water decreases when the number of dissolved molecules (or better particles) in the solvent increases. This is called freezing point depression and you can easily find the relation between the quantity of particles dissolved and the freezing point on Wikipedia.
What is the freezing point of Cranberry juice?
Orange Juice freezes at 0 degrees celsius:P
Where is mechanical weathering likely to find to occur more quickly where the winter temperature usually stays below freezing or where it more often shifts back and forth around the freezing point?
WARM
Can you please send me a diagram to make a model of nuclear reactor?
Wikianswers does not do diagrams. If you go to Wikipedia article on Pressurised Water Reactors you will find a diagram there.
What is the effect of decreased pressure on the boiling and freezing point?
As pressure decreases, the boiling point of water will also decrease. Backpackers camping in the high mountains are familiar with the phenomena when they get water boiling - and find that it is still only lukewarm because the atmospheric pressure at their high altitude is so low.
What tool does a scientist use to study the freezing point of water?
What scientists studied freezing point of depression? I can't find any.

Which state of matter would you expect to find water at 20 Celsius on Earth?
In a liquid, as at sea level water's boiling point is 100 degrees and it's freezing point is 0.
What are the materials for salt water freeze?
Salt lowers the freezing point of water by the amount of molals of NaCl in the solution. 0°C - 1.86(°C / molal) (NaCl molal). This will find the new freezing point and if the energy is enough to bring salt water below this temperature and turn the solution into ice then the salt water will freeze.
What is the freezing point of Ajax dish detergent?
That sounds like a great science experiment to me - so far as I can find, nobody has tested that yet, so you could be the first person to find the correct answer! It's probably going to be lower than the 32 degrees Fahrenheit freezing point of plain water, because it's got other chemicals in it besides the water.
How do you find food in the freezing area's of the world?
If there is water that is clean then i would say fish and animals on the freezing area.
What is the freezing point of butter?
Butter does not have a single freezing point. It actually has two sets of freezing processes. The first is the water phase freezing. If you tried to freeze salt water -- you'll find that water keeps "coming out of solution" and freezing until you hit a point called the "eutectic" point, where it then freezes solid. The earlier freezing tends to be mushy. Thus, salt water ice is soft. The second freezing process is the shifted from a liquid fat to a solid fat. Again, because of the structure of the fats, the freezing point varies over a very large range. So again you don't get a "hard" structure until you are at a very cold temperature. In addition, the fats in butter may undergo solid to solid transformations that will lead to texture changes as the fat takes up different crystal structures. Thus, butter is a very complex material with many different freezing points. Source: http://www.madsci.org/posts/archives/2000-03/953730434.Ch.r.html
What is the freezing point of a solution that contains 2.0 mol of CaCl2 in 800.0 g of water Kf for water equals 1.86Cm?
2.0 mol of CaCl2 releases 2.0 mol of Ca+2 ions & 4.0 mol of Cl- ions = 6 moles of ions find molality: 6 moles / 0.800 kg water = 7.5 molal solution dT = kf (molality) dT = 1.86 C (7.5m) dT = 14 Celsius drop in freezing temp the new freezing point is - 14 C
How does sugar baking soda and salt melt ice?
sugar is just like salt. it will lower the freezing point of water. Baking soda will do the same thing because it is a kind of salt so it will also lower the freezing point but salt has the most effect.
Would something freeze and melt at the same temperature?
This is a strange question. Water boils usually at 100 degrees Celsius and freezes at 0 degrees Celsius. Who understands this question? I think you mean "If a substance changes from solid to liquid when the temperature exceeds 100 degrees, will it change from liquid back to solid when cooled to below 100?" Yes, it will.
Do salt water freeze faster than sweet water?
How much salt and how much sweet?By the way, which freezes "faster" is not a question that scientists tend to study a lot. They're more likely to be interested in the freezing point. At the same temperature, something with a lower freezing point will probably freeze slower, but quantifying this is complicated.Anyhow, that aside, adding any solute to a solvent lowers the freezing point. The amount the freezing point is lowered depends on the solvent and on the amount of solute that was added (measured in moles). Solutes that dissociate into multiple species in solution count multiple times (so adding one mole of table salt, which dissociates into one mole of sodium ions and one mole of chloride ions, lowers the freezing point of a certain amount of water twice as much as adding one mole of sugar, which doesn't dissociate). However, remember that it's the number of moles, not the volume or weight directly, that matters.If you have specific quantities in mind, you could calculate the molality of the resulting solutions (remember that table salt counts twice) and multiply that by the molal freezing point depression of water (about 1.85 K kg/mol) to find out exactly how much the freezing point was lowered in each case.
