beacuase they were all water, the difference is the mineral content which are negligible or has no bearing on the water density.
they all contain same elements of Periodic Table
the only differences are stuff dissolved in them, which are so minimal they make no difference to density or structure
Salt or NaCl has a density of 2.16 ish g/ml. Water or H2O has a density of 1 g/ml. so thus we can suggest that salt water has an average density of 3.16 g/ml. Tap water is made up of H2O 1 g/ml and small mineral deposits from the lake or river it was pumped from, these normally have almost no affect on most measuring equipment , However you also need to take into account the chemicals such as chlorine Cl who's density is 3.214 g/cm3 Many city's use chlorine in tap water.
The density of salt water is more dense than fresh water, because not only are there water molecules, but also sodium molecules crammed in between the water molecules.
=====
Water has the formula H2O (two hydrogens, one oxygen)) The main component that makes salt water SALT water is Sodium Chloride, which has a formula of NaCl. Hydrogen (H) has an atomic weight of about 1, Oxygen (O) has an atomic weight of about 16, Sodium (Na) is about 23, Chlorine (Cl) is about 35.45. If you substituted one NaCl molecule for one water molecule you would obviously have a lot more mass. Granted, the NaCl molecule and its ions are a bit larger than water, but not enough to compensate for the increased mass - hence the greater density of salt water.
There is not such a big difference, its approximately same.
salt water because there is desolved salts in the water make it denser. pluss it has other disolved parts in it too!
yes it is. remember that distilled water is more pure and top water has allot more dissolved solids and gases present.
Salt water is denser because t contains many things in it while tap water is filtered
The seawater is a saline solution; consequently, compared with tap water the density is greater - as an average: 1,025 g/cm3.
Tap water and rain water have the same density because they're both the same thing, though usually tap water is slightly cleaner.
tap water can vary but on average tap water is denser
When salt water is poured into a glass containing cold tap water, the salt water will collect and settle at the bottom of the glass. This is due to the salinity and density of the salt water.
Objects that contain a higher density that water will sink, but if the same object has a lower density that saltwater, then it will float in salt water. And this also depends on the concentration of sodium ions present in the salt water. As the concentration of the sodium ions increase, the density of the salt water increases.
Tap water
tap water will evaporate the fastest
Because tap water contains salt in some amounts
because salt is higher density than water and dissolves in the water, increasing density
The density of the fresh water is less than the density of the salt water.
salt water is different from tap water. when salt is added to water it converts the tap water to salt water. This increases the density of the water, and allows more objects to float above it. remember, when objects are mixed like that, the greater the density, the further it is from the surface.
Salt water due to sediments of salts.
When salt water is poured into a glass containing cold tap water, the salt water will collect and settle at the bottom of the glass. This is due to the salinity and density of the salt water.
yes an egg can float in salt water but it depends on the density of the water.
Objects that contain a higher density that water will sink, but if the same object has a lower density that saltwater, then it will float in salt water. And this also depends on the concentration of sodium ions present in the salt water. As the concentration of the sodium ions increase, the density of the salt water increases.
Tap water, salt water will kill them
Plain Tap water would freeze fastest.Adding salt or sugar to tap water will cause a depression/decrease in freezing point. Hence it will be harder to freeze the tap salt or sugar water.
because following the density principle, the density of the egg compared to the density of the tap water is lesser....(the density principle states that an object or substance with lesser density will float on the surface of the substance or object which has the greater density...).....now,,,with salt,,, salt makes the density of the tap water to increase and increases also the salinity of the water making the egg float because the density of the water with salt is now greater than the density of the egg.... An egg will float when the density of the water is greater than the density of the egg. Adding salt increases the density of a salt water solution. Whether the egg floats or sinks depends on the condition of the egg as well as the amount of salt in the water. If an object is LESS dense than the solution that it is in, then it WILL float. If an object is MORE dense than the solution it is in, then it WILL NOT float. An egg is more dense than regular water; therefore, the egg will sink. But when you add salt to the water, you are making the solution more dense. The salt water's density becomes greater to the point that it is more dense than the egg. Because the egg is now LESS dense than the water, it floats.
salt water and tap water
No tap water doesnt have salt as it goes through several filtres before reaching your tap.
