If an object sinks in water what is its density as compared to the density of the water?
If the water is denser than the object it will definitely float.
However a denser object will not always sink.
The idea of something "sinking" depends on what action you are talking about. It is obviously true that very heavy boats do not "sink" but float happily on the surface of water. (Imagine a simple aluminum row boat where aluminum is almost three times the density of water.) If the boat is submerged however, it stays submerged. The operative principle of physics says that the boat displaces a volume of water with a weight equal to the weight of the boat that is floating, so obviously boats are shaped the way they are to displace enough water to keep them above the surface.
So, the simple answer is that an object with a density greater than water will not float to the surface if it is submerged but an object with a density less than water will float to the surface.
If you wish to consider complexities beyond merely the density, then you can include the phenomenon of surface tension in keeping small objects floating even if they are more dense than water. That is a small force relevant for small objects and a topic of such complexity that it is not likely to be part of the answer to the question that was posed.
What else can I help you with?
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
How can you determine whether a soild object is more dense or less dense than water?
You can put a uniform object into water.If it sinks density is higher than water,if floats lesser than water.If you can place anywhere in water,density is equal to water.
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.
How does the density of an object that sinks into a fluid compare to the density of the fluid?
Oh boy. Density is the mass per volume...grams per cubic centimeter, tons per cubic yard, whatever. Water's density is one gram per cubic centimeter. An object with lower density than water will sink into water until the number of cubic centimeters corresponding to the mass of the object are below the surface of the water. If the object is 100 cubic centimeters and it weighs 50 grams, half of it will be below the surface and half above. This is buoyancy, or "floating." Cool so far? If an object's density is more than one gram per cubic centimeter, the whole thing will be below the surface of the water. Because the water can't support the weight of the item, it will sink to the bottom given enough time. If it sinks, its density is greater than water...but without weighing it, we can't say how much greater because an item with mass of 5 grams and density of 1.1 grams per cc will sink as surely as a 300-pound anvil with density of 7.2 grams per cc. It just won't do it quite as fast.
Why doesn't a sugar cube float in water?
A sugar cube sinks in water because it is denser than water. The density of an object determines whether it sinks or floats in a fluid. Since the sugar cube is denser than water, it displaces less water than its own weight, causing it to sink.
If an object sinks in water its density is less than that of water?
Yes, that's correct. If an object has a density lower than that of water, it will float. If it sinks, then its density is greater than that of water.
Is floats or sinks in water a physical property?
Yes it is because mass and density are physical properties and density is how you can tell if it is going to sink or float. to find out density, you divide the mass by the volume of an object.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
What happens if an object of higher density is placed in water?
Higher than what ?? If the object's density is higher than the density of water, then the object sinks in the water.
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.
When this material is placed in a container of water it sinks to the bottom of the container compared to the density of water the density of the material is?
The density of the material is greater than the density of water if it sinks to the bottom of the container when placed in water.
What of a mineral will determine if it floats or sinks in water?
The density of the mineral compared to the density of water will determine if it floats or sinks. If the mineral has a lower density than water, it will float; if it has a higher density, it will sink.
If an object sinks in water what is its dencity?
More than the density of water.
Is mass what makes things float or sink in water?
The density of an object compared to the density of water determines whether it will float or sink. An object with a higher density than water will sink, while an object with a lower density will float. Mass does play a role in determining density but is not the sole factor in whether something floats or sinks.
When this material is placed in a container of water it sinks to the bottom of the container compared to the density of water the density of material is?
The density of the material is greater than the density of water because it sinks to the bottom of the container. Objects with a density greater than that of water will sink in water.
Does a solid block that sinks in a container of water has a lower density than water?
Yes, a solid block that sinks in water has a higher density than water. Density is the mass of an object divided by its volume. If the density of an object is greater than the density of the fluid it is in, the object will sink.
Why needle sinks in water?
As we know that the ratio of the density to the volume is inverse relation. As the volume of the object is lesser, than the density will be greater.So the condition of floating bodies depend upon the weight of the displaced liquid.If the object(needle) is denser,so it will not be able to displace more liquid.Therefore needle sinks in water.
