Why do you float in water but not in air when the gravitation is the exact same?
The air is less dense than your body, so you sink through it. The opposite is true for water, which is more dense than your body, so you float in it.
No. If it was ice would float on water vapour! They might have (close to) the same density because water expands when frozen OR heated. I'm not sure of the EXACT density for both.
No. Salt water is denser, so you float higher in it.
An object which is denser than water can float on water when it has a specific shape which lends it buoyancy. For example, a sheet of iron will not float on water but if the same sheet is bent in shape of a bowl, it can float on water.
Just the same as you do in shallow water.
no because it comes in bubbles that float,for example if I opened a bottle of water there it would float!
No. Oil will float on vinegar as vinegar has the same density as water.
Oil/petroleum (gasoline?) will float on top of water as well.
Playdoh can float depending on how dense it is. It also depends on what your floating it on. If you float it on water than it has to be less dense than the water, same with other liquids.
Relatively speaking, all water vessels float upon water of the same density.
The stone is heavier than the same volume of water. In short the density of the stone is more than the water. So the stone does not float on the water.
A bottle, though heavier than water, can be made to float by trapping air inside of it. This same bottle can be made to sink by filling it with water, or a substance heavier than water. It can again float by emptying it and trapping air in it.
Metal ships are built to float.
things float because they are less denser then the water. second things do not float, the molecules from the water support the molecules from the thing on the water. that is how something heavy can float. it just has to be boyent meaning it is spread out enough so there is more water molecules to hold it up. if you mean in the air it is the same concept.
They are not. Gravitation is a force and forces (if they can overcome friction) will cause accceleration. The two are not the same.
the same way a peice of wood would float if you threw it in the water, except these are covered with a coat that keeps water out, unless you ding it
Put an egg in fresh water and it will sink. Put the egg in heavily salted water and it will float near the surface. This is because the salt makes the water more dense and able to support more weight. The same goes for a ship. A ship will settle lower in fresh water and the same ship will float higher in the oceans.
Only in water. The air from your mouth is the same density as the air in the room- they will not float in air.
Not really. Salt water is denser(that's why you float better in the sea), so pressure will be greater.
The same way anything floats, by displacing an amount of water that weighs as much as it does. Airplanes that are meant to float on water typically either have boat-like hulls or floats whose purpose is to displace enough water to allow the airplane to float.
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.
It doesn't float or sink in the water that means that the egg has the same density as the water.
for the same reason anything floats. they are less dense then water
It's down to density, as in, amount of mass per cm², or set area. If the object is less dense than water, then it will float; If the mass in the same amount of mass of the water displaced is less, then it will float. So heavy objects with lots of air inside weigh less than the same area of water.
when jellyfish reach adulthood they are about 95% water, so they are about the same density as water.
Neither, it has neutral buoyancy so will remain where placed.
For something to float, it must displace the same amount of water as it weighs. Answer: To float in water, a solid metal object must be lighter than the water equivalent to its volume. This would make lithium (at S.G. 0.53) the only metal that would float in water. Objects which are hollow and made of metal float because the contained volume of the object divided by the weight of the object is less than… Read More
Salt water is more dense than fresh(tap) water. This allows the egg to float. It is also easier to stay afloat in the ocean than in a fresh water lake. Same concept. how much water do i use?
No since water and water is technically the EXACT SAME THING!!!
A cork is able to float on water because it is less dense than the water. The reason why is because an object with more dense then itself it will float and an object with less density will sink in the fluid. HOWEVER if the object (such as the cork) has the same density, the object will neither float nor sink; instead it will stay at the same level in the fluid. So TECHNICALLY it… Read More
anything that displaces more than its own weight in water will float. For example if you have a solid plastic toy that weighs less than the same amount of water it will float above the water. This is why steel ships can float, because although the steel is much denser than water, the amount of water displaced by the ship weighs more than the ship itself (because of all the air inside).
They would float the same unless one is different sized than the other; although the ice would melt in warm water; therefore getting smaller. Another answer: The more dense the liquid, the higher the ice(solid) will float. Cold water is more dense than warm water, so the cube will float higher in colder water than warm.
Depending on the weight of the leaves, some will float to the top to give off their flavors to the boiling water, or will float to the bottom to accomplish the same task.
Buoyancy, the total weight of the vessel has to displace that same weight of water. If the volume of the water displaced is less than the volume of the ship, or any other object for that matter, then it will float.
Indefinitely. Someting will float as long as its density is less than that of the fluid it is suspended in. So a baloon will float until the volume decreases to the point it is more dense than air or diffusion exchanges enough gas for the same to happen. Some wood will float in water until it absorbs enough water to no longer be less dense than water.
no most of your body that isn't water is less dense than water, that's why humans usually float.
Yes, As you dissolve the sugar into the water the volume of the water will stay the same (once the sugar has gone into solution) but the density of the water/sugar solution will have increased (there is more mass in the same volume). Thus, because when you float something it displaces a volume of liquid equal to its mass/weight, in a sugar solution the floating body will float higher because its mass/weight will be compensated… Read More
Because of the density of the salt and baking soda.
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.
no difference same exact molecule
This had to do with density. When you put the egg into the water, it sinks as it is more dense than the water. However, if you add salt in the water, it becomes salt water and makes the water more dense than the egg so the egg can float. It is the same reason why people float in the dead sea. The dead sea is very salty and is more dense than humans. That's… Read More
Neither, it just stays submerged, provided its density stays the same as the water around.
the amount of water does not affect the overall buoyancy of objects, at least, that is to say, once the object is being fully supported by the water. That means that there is enough water to suspend the object completely over the base. An object that is denser than water will sink to the bottom (if you assume that the water is pure, of course) at the exact same rate in a 20 liter tank… Read More
The human body have a density of 62.4 pound per cubic foot, water has ,( to my knolage ) the same density , therefore letting one float on water, so i would have to say the human body is the SAME density as water.... :)
Water is fairly heavy. Metal, Rocks, etc. are heavier. When an object is made of a material heavier than water, its shape determines whether or not it will float. Most metal balls sink. Most metal buckets float. If the weight of water a bucket can hold weighs more than the bucket itself, then the bucket will float. The same is true for any object. The principal is called displacement.
If you sink, then you weigh more than your volume of water. If you float, then the volume of water you displaced weighs the same as you weigh.
No - Corundum is roughly 4 times heavier than a same amount of water.
when the density of the egg and water causes by salt, are fairly equal the egg shall float in the middle when both of their density is close or the same.
No. water vapour is invisible. Fog is tiny droplets of water, where water vapour has condensed into liquid water (droplets small enough to "float").
Because it doesn't matter how much salt you put into the water to make it float. Is it because the density is the same no matter how much salt you add?
Balloons float because of the same principal as how ships float: bouyancy. A ship displaces a volume of water. If the ship's weight is less than the volume of water that it displaces, then it will float. Same is true for a balloon. It displaces a volume of air. If the Hydrogen or Helium in the balloon weighs less than the volume of air it displaces, then it will rise.
