When salt makes the water more dense how does it make things float?
Because salinated water has more atoms per mole of the compound, it makes this solution denser than pure water. The heavier a solution is the more force that can be applied to it without breaking its surface. Think of trying to float in air, or to float in water. You are able to float in water because the substance is much denser than air. You will have a much easier time floating in the Dead Sea (the most salty body of water in the world) than floating in a fresh water body of water, which has much less salt in it.
Things float in water if they are less dense than the water they are floating in. Putting salt in the water makes it more dense, so things that are a little more dense than ordinary water float in salt water.
It makes the water more dense.
salt makes the water denser, so things that are now less dense than the salt water will float
not exactly. things that are less dense than water float. salt makes water more dense and therefore more things can float in it. ============================= (Notice that your rubber duckie floats in the bathtub, even though t here's no salt in your bath.)
It has to do with how dense things are. If it is equal to or less dense than water, it will float. If it is greater, it will sink.
Its density. If a substance is denser than water, it will sink. If it is less dense, then it will float. (The surface tension of water also contributes slightly to this.)
Freshwater is less dense than saltwater, and so it tends to float on top, as less dense things tend to float on denser things.
Because water is more dense then our bodies so when things are more dense they sink to the bottom and when they are less dense they float to the top
the salt makes the water more dense so the egg is less dense than the water making it float.
Things that float are less dense than water.
The density of oil is what makes it float on water. Oil is less dense than water and does not mix or dissolve within the water. Therefore, it floats. The density of oil is what makes it float on water. Oil is less dense than water and does not mix or dissolve within the water.
I would be thinking the salt is the reason. The salt makes the water more dense, so things that were more dense as compared to the water before become less dense as compared to seawater. So yeah, that's why things are more buoyant in seawater.
Puffing it up makes it less dense. Anything less dense than water can float on water, and anything more dense than water will sink.
Buoyancy is a property that states that if an object is less dense than water it will float. Since salt water is denser that fresh water, things that were previously more dense than fresh water can float in water that is more dense (salt water).
Because they are less dense than the water.
Well... The salt in the water makes the egg float because the water becomes more dense than just plain water
things float when their mass is less than that of the water, meaning they are less dense than the water. hollow objects always float because open air is less dense than water
The salt makes the water more dense.
It's less dense than water.
An egg can float in flour water because the flour that is added to the water makes it more dense.
because tin foil is less dense then water so it makes it float!!!!
It is more dense than water, so when it dissolves in water, it raises the average density of water, so more objects can float more readily in the solution.
If something is less dense than than the liquid or a gas you put it in then it will float.
Apples are 25% air which makes them less dense then water.
flotation is due to the fact the boat is less dense than the water, salty water is more dense than normal water. Consequently things can be heavier or more dense and still be less dense than water aka they float.
Yes. For every fluid, there are things that float in it ... they just have to be things that are less dense than the fluid. That's how stones float in mercury, logs float in water, and hot balloons float in air.
The salt makes the water more dense ,so that objects can float on the water.
They are less dense than water. More dense things sink. Density refers to how tightly the atoms are packed.
Cork Cells float because they are filled with air which is less dense than water is. - NE
Density. It depends how dense the fruit is and how much water there is. Suppose you had a 1" by 2" aquarium full of water, and you dropped an apple in it. The apple would float, because it would be less dense then the water.
For an object to float in water it has to be less dense than the water.
All fruits do not float in water. Some fruits float due to their peel, like lemons or oranges, which makes them less dense than the surface tension of the water.
Water floats when it is turned into ice, because in this form it is less dense (it crystallizes, and the structure expands). It also can float in combinations of liquids, for example, it is less dense than liquid mercury, but more dense than oil, so it would 'float' on the mercury. Liquid mercury is very dense, and doesn't usually float on things.
It is quite common for various things to float in water. But any liquid can cause things to float.
Styrofoam is mostly air, trapped in little cells inside plastic. It's like the plastic version if Rice Krispies, which also float on water. Until they get soggy and sink. Air floats because it is less dense than water. Other things, like oil, are also less dense than water and float on it. Some things, like most rocks, are denser than water and sink in it. If you haven't figured it out yet, whether something floats… Read More
There is so much salt in the water that the water becomes really dense, so you can lay on your back in the water and just float.
An object must be less dense than water in order to float on water.
An object's density is related to its weight and size. If the density is less than that of water, it will float on the water. If it is greater than that of water, it will sink. Water is not very dense - most things don't float on water. This is because they are denser than it and it cannot support them.
The density of a stone is higher compared to the density of water.
Yes , because salt adds density to the water making it more dense than the egg - which makes the egg float ! (:
What does the statement 'the buoyant force of a liquid does not depend on physical statebut on density' mean?
Floating, or buoyancy, depends on the density of the liquid and the density of the object. Water is a pretty dense liquid, and things float in it; they are buoyant. Oil or gasoline are less dense; things that float in water may not float in oil.
Ice is less DENSE than water. This seems odd, as we usually expect colder things to become more dense than their warmer counterparts. But the hydrogen bonding in water makes it expand just below freezing, and so ice becomes less dense than water, and so it floats.
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
it depends on how dense the object is if it is more dense than the water it will sink if it is less dense than the water it will float.
Because the boat has a special shape that makes it less dense than water.
Objects will float on water because they aren't as dense as the water itself. A ship will float because there are a lot of compartments filled with air, which is not as dense as water. The above answer is also valid but according to the Archimedes Principle, the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object.
Liquid water is denser because when water freezes, the water particles spread out as they solidify. This means that the same amount of particles take up more space, causing the density to decrease. Ice is less dense also because ice cubes float on liquid water. Less dense things float on more dense things.
The more salt there is in water the more buoyant an object is. The salt makes the water dense. Objects only float if they have less density than salt.
they are less dense than water, which makes them buoyant. This is a result of the air that is trapped in their thick fur.
Because water as a solid (frozen) is not as dense as water as a liquid. Less density makes it lighter, which is why it floats.
