The density of the liquid water is rho = 1,000 kg/m3 or 1,0 g/cm3.
SI standard for density rho = mass m / volume V in kg/m3.
A fish should have a very similar density to the water it swims in. Archimedes' principle states that the buoyant force on an object is equal to the weight of the water it displaces. The total vertical force on a fish is that of gravity, the buoyant force, and any reaction force generated by swimming. If the fish were much denser than water or saltwater, as the case may be, the weight of the displaced water would be much less than the fish's weight, and the fish would sink. If the fish were much less dense, then the fish would float to the surface. To keep at a desired depth, perhaps with a little help from swimming, the fish should be about as dense as the water it swims in.
Many fish have a swim bladder, also called a "gas bladder", which fills with a gas, usually oxygen, and which helps regulate the fish's average density. The rest of the fish then is a bit denser on average than water.
What else can I help you with?
What does gravity spicific mean?
Perhaps you mean "specific gravity". That refers to an object's density, compared to the density of a reference subtance (usually water). For example, if iron has 8 times the density of water, then its specific gravity is said to be 8.
Why do ships sink more in fresh water than in salt water in respect to freeboard?
It is because the fresh water has less density compared to that of salt water.
What is the density of water vapor in relation to the air's density?
I sugest you look up "steam tables". Since convection currents are caused solely by diferences in density ... yes, it is assumed that tempreture diferences CAUSED the density gradiant - but that is not always true.
An object less dense than water will in water?
The "average" density of the object must be less than that of the water displaced.
How is the density of a fish controlled?
Fish control their density with a gas-filled organ called a swim bladder. The average density of a particular fish's tissues, not including gas in the , is 1070 kg/m^3.
Does water have a high density compared to other substances?
Yes, water has a relatively high density compared to many other substances.
Does Alcohol have a high density?
Well that depends, do you think 0.79 grams is high? Compared to water, which has a density of 1.0 grams.. so does alcohol have a high density compared to water? No. :P
How do fish use density in order to move in the water?
Fish use density in order to move in the water since they do not have lungs. When the density of water keeps changing, fish use it to move and thereby using less energy.
What is styrofoam density compared to water?
The density of styrofoam is lower: about 0.028 to 0.045 times that of water.
What is the density method?
mass / volume = density relative density is that compared to water ( 1g / cm3)
What is the effect of sugar compared to water on density?
Sugar has a greater density than water. This is obvious from the fact that it sinks in water. If you add sugar to water, the water's density increases.
How do you calculate the relative density of a substance?
To calculate the relative density of a substance, you divide the density of the substance by the density of water. The formula is: Relative Density Density of Substance / Density of Water. The relative density is a measure of how dense a substance is compared to water.
What is the method?
mass / volume = density relative density is that compared to water ( 1g / cm3)
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 do you mean relative density?
Relative density is a measure of the density of a substance compared to the density of another substance, usually water. It is calculated by dividing the density of the substance by the density of water. Relative density can help determine if a substance will sink or float in water based on its comparison to water's density.
Is the density of rubber stopper is denser than the density of water?
No, the density of a rubber stopper is less than the density of water. Rubber has a lower density compared to water, so a rubber stopper would float on water.
What is Compares is an objects density to the density of water?
Specific gravity is a measurement that compares the density of an object to the density of water. It tells you how much heavier or lighter an object is compared to an equal volume of water.
