How does the density of a rock affect its ability to float?
If the density of ANY object is less than 1.00, then it will float in fresh water. If the density is greater than 1.00, the object will sink in fresh water. If the object's density is precisely 1.00, it will be "neutrally buoyant" and will neither rise nor sink; it will remain at whatever depth you place it.
Why does salt water make stuff float than fresh water?
Salt water has a greater density than fresh water. So the same object will foat higher in salt water than in fresh, and some things will foat in salt water that are too dense to float in fresh water.
What can you say about the density of a paper clip versus the density water?
Paper clips have a density greater than the density of water.
Why do hings float better in salt water than freash water?
Things float better in salt water than fresh water due to the mass and density of the salt as opposed to that of the water. Sodium chloride (Being the classic "salt" people are familiar with) has a density of 2.165 grams per cubic centimeter, while water has a density of 1 gram per cubic centimeter. Thus, when the two are mixed and the salt dissolves evenly throughout the solvent (water), the density increases. At least, in layman terms. Now, an object sinks in a fluid when the density of that object is greater than that of the fluid. Since fresh water has a density of 1, and salt water has some density greater than that (dependent upon how much salt is dissolved in it), then more objects will likely have a density greater than that of the less dense fluid (fresh water) than that of the more dense fluid (salt water) With that logic, fewer objects will have more density than that of salt water, and therefore, more things will float in it.
What is the comparison of density to density of an equal volume of water?
If the density of a substance is greater than the density of water, it will sink in water. If the density of a substance is less than the density of water, it will float on water.
Why does seawater have a greater buoyant force than fresh water?
Seawater has a greater buoyant force than fresh water because seawater has a higher density than fresh water therefore the buoyancy is higher. *Improved* This happens because when water mixes with the salt in sea water, the density changes to the average density which is around 1.55 g/mL (Average density is the density of different materials put to together )
Why does an egg sink in fresh water but sink in salt water?
Eggs, water, floating.An egg doesn't float in fresh water but since salt water is more dense than fresh water, it has a better chance of floating in the salt water. The greater buoyant force allows the egg to float in the salt water, if salty enough.More explanationAn egg sinks in fresh water but not in salt water because fresh water is not as dense. In order for something to float, the buoyant force has to be greater than or equal to the weight of the object. The buoyant force is equal to the weight of the liquid that is displaced by the object. To figure out the weight of the water displaced you multiply the density of the water by the volume and then multiply that by gravity. The density of the fresh water is less than the density of the salt water, therefore the weight of the water displaced will be greater in the case of the salt water, resulting in a greater buoyant force.The more salt in water the more bouyant an object becomes. The salt makes the water more denser. Check out the dead sea. Most salt content in any lake or sea. The density of the salt water is greater than the density of the egg. Items sink if their own density is greater than the density of whatever they are trying to float in. Items float to the top if their density is less than the density of what they are floating in, and items hang in the middle if the densities are the same. Adding in the salt gives the water a greater density than the water did had before, so the egg doesn't float in freshwater.Did you know?A fresh egg will sink in fresh water but it will float in salty water. A rotten egg will float in fresh water.

Why do some things float in salt water but not in fresh water?
Because salt water can carry more objects than fresh water because the salt in the water makes the water heavier, and because fresh water has nothing in it so it's less heavier. Water cannot carry something heavier than itself. This heaviness is called density, and is the mass of the water in a particular volume of water. Pure fresh water has a density of 1g/mL, which means each milliliter of water has a mass of 1 gram. Anything that has a density greater than 1g/mL will sink in fresh water. The density of salt water is greater than 1g/mL, so anything that has a density less than the salt water will float on it, including fresh water.
Why do ship float better at sea than in fresh water?
Sea water has salt, and therefore a higher density.
Why is it easier to float in saltwater than in fresh water then in fresh water?
Because salt is dense, so denser the water the better you float!
Which has greater density ice or water how can you say that?
Water has a greater density than ice.
How do you know an object has a density greater than water?
If an object placed in water sinks - then it has a density greater than water.
How does the density of a rock affect its ability to float?

If the object's density is precisely 1.00, it will be "neutrally buoyant" and will neither rise nor sink; it will remain at whatever depth you place it.
What density does an object have to have to sink in water?
A density greater than that of water (which varies with temperature).
If an object sinks when being placed in water its density is?
To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.
Why does salt water make stuff float than fresh water?
Salt water has a greater density than fresh water. So the same object will foat higher in salt water than in fresh, and some things will foat in salt water that are too dense to float in fresh water.
