What are the effects of impurities in boiling and freezing point?
AnswerImpurities tend to increase the boiling point and lower the freezing point.in a way boiling point of salty water > boiling point of fresh waterfreezing properties of salty water < freezing properties of fresh watermelting properties of salty water < melting properties of fresh water.Salt water, contains NaCl, which ionizes into Na and Cl ions. when ions are added to a solvent, such as water, they tend to increase the boiling point and lower the melting point.
Will an apple float or sink?
Apples float. Hence the challenge of "bobbing for apples," trying to grab apples floating in a tub with your teeth. The trick, like the trick in a pie eating contest, is to drive your head in as deep as you can. Bite the apple at the bottom of the tub.
Why does a perspex block sink in fresh water but floats in salty water?
salty water is more dense than fresh
Does eggs float better on salt water or fresh water?
viscosity of saline water is higher than that of pure water
Which water will hold up an heavy object longer salt water or tap?
Salt water weighs more than fresh water by 2.5%. Yes. Salt water from the ocean weighs approx 8.55 lbs per gallon and fresh water weighs approx. 8.34 lbs per gallon, so that is 2.5% greater density of ocean water.This is approximate because the more salt dissolved in the water the more it will weigh. (For example water from the Dead Sea would weigh more than ocean water) Also, as water gets colder its density increases until it is 4 degrees centigrade above freezing, at which point it begins to expand and then expands abruptly when it forms ice. The salt concentration affect freezing temperature and temperature effects density, so the 2.5% greater density is reliable only for the middle temperature range, away from freezing and boiling.When one solute (the substance getting dissolved) dissolves in a solvent (the substance doing the dissolving) the solute fills in the spaces between the molecules. (Yes, it's true. There is actually space between molecules. If you would like to prove that to yourself, mix exactly 50 milliliters of water with 50 milliliters of rubbing alcohol and see how much you get. It's cool!!) (Lest you think this is always true, there are other examples of mixing two liquids which result in an increase in volume. That requires a more detailed explanation.)When salt (the solute) dissolves in water (the Solvent), the ions of sodium separate from the ions of chlorine and enter the spaces between the water molecules. In this process, the salt adds to the mass of the solution but the volume added is less than the volume of the original salt. To be specific, if you added one cubic centimeter of salt to a liter of water, you would find the water increased in volume only about a half of a cubic centimeter. Since a cubic centimeter of salt weighs more than a cubic centimeter of water, the density of the salt water has increased.So, salt water does weigh more than fresh water. The most amazing thing is that this difference in weight, more accurately the density, drives the largest ocean current in the world called the Thermohaline Conveyor. It's pretty cool.
Why does an egg float in water and not it salty water?
A fresh egg don't float in pure water; in a salty water the floating depends on the concentration of the salt in solution. The salty water is more dense.
When the increase in the salinity of seawater result in an increase or decrease in density?
If you compare the density of sea water, and then compared the extremely salty Dead Sea, you will find that the more salt in the water, the higher is the density. Which is why you can float on the Dead Sea while reading a newspaper (which I once saw demonstrated in a documentary). Also, a ship will float lower on a fresh water lake, and float higher on salt water.
Why goat cheese are salty?
Salt is added to preserve it.
What is the Density of salt water per gram?
depends on how salty it is.. It is 5% salt water
Relation of Salinity and Total Dissolved Solids?
Density depends on salinity to tell how dense something is so if you had a cup of salty water and a cup of not salty water, then the salty water would be denser than the cup of not salty water.
What Rocky Mountain region lake has water that is four times as salty as the ocean which makes it very good for floating?
Salt Lake
Should you increase your water consumption after a salty meal to flush out the salt?
It is not completely necessary because the body can keep a constant internal environment via homeostasis, however it is advisable to increase water consumption after a salty meal.
Why does physical change differ from a chemical change?
As a basic example: When a block of ice melts into water, the change is physical (solid to liquid) yet the chemical contents of the ice/water remains unchanged. If a lot of salt is then dissolved in the melted water, it is still water, yet it has changed chemically into a saline (salty) solution. The added salt will increase the water's density - which could be a physical change!
Which type of water is not salty and has little or no taste color or smell?
Freshwater is not salty. Saltwater is salty.
Does the volume of salty water increase when its temperature increases?
Yes, though it is slight, the volume increase is measurable when the temperature of salt water increases.
How salty does the sea have to be before an egg floats?
the sea has more density than the egg so the egg floats
Is there anything that can be added to the soil which will make fruit sweeter?
some fruits will be sweeter if the water is salty
