An object floats when its density is lower than the liquid it is being compared with (the liquid it floats on) and it sinks when its density is higher than the liquid it is being compared with.
The expression for the energy density in terms of stress and strain can be expressed as ρe.
The terms are when a investigator go to the crime scene make sure to check for clues
No. Because if you try to float in the air, you'll just fall. :( thats general answer use some scientific terms
He explained them in terms of descent with modification, common descent and natural selection.
Charles Lyell
Density is how well an object would float when put into water. Water has a density of 1, so if the object floats, it's density is less then 1. If the object sinks, then it's density is greater then 1.
When the density of a object is less than that of the surrounding fluid, the buoyant force is great enough to move it up.
Heating the air inside the balloon decreases its density due to Charles's law, which states that as temperature increases, volume increases assuming pressure is constant. The lighter, less dense air inside the balloon creates a buoyant force greater than its weight, allowing it to float in the denser, cooler air outside the balloon.
A life jacket is also known as a floatation or buoyancy aid - it acts to increase your buoyancy. So what do we mean by this? Well, buoyancy can be described simply as how easily an object will float in a fluid (or gas), where the more buoyant the object the better it will float. Buoyancy is related to the density of an object which is in turn related to the amount of mass a given object has relative to it's volume. As the density of an object gets larger compared to the density of the fluid it is floating in, its buoyancy will decrease and it will become less able to float. As the density of the object becomes larger than the density of the fluid it is floating in, it will sink. Now that we understand buoyancy, we can explain how a life jacket works. A life jacket is mainly filled with gas which has a very low mass. As such when worn by a person, it acts to significantly increase their volume for only a very small increase in their mass. This means that they have a lower density than normal which increases their buoyancy and helps them to float.
A body whose total density is greater than that of water will sink in water;that is, if it's not supported, it will continuously drift lower.A body whose total density is less than that of water will float in water; that is,it will sink only partially, and will then remain on the surface and sink no lower.A body whose total density is exactly equal to that of water will have "neutral buoyancy",and will "float submerged" so to speak. That is, none of it will remain above the surface,but once submerged, it will neither rise nor sink further, but will maintain the depth at whichit is placed.
In a plasma, especially an extreme case like the interior of the Sun, things can get tricky. This is a fluid, but the energy density of electromagnetic energy is high and it "flows" through a process that is really not adequately characterized in the terms we normally use for radiative heat transfer. Instead, terms like "photon diffusion" are used to explain the process.
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.
they have more mass
The belief in supernatural is the belief in things that can't be explained in the usual scientific terms.
The expression for the energy density in terms of stress and strain can be expressed as ρe.
An object will float when submerged into liquid because its density is less than that of the liquid. As described in Archimedes' Principle, the buoyancy forces on an object will be equal to the weight of the liquid displaced. If the density of the object is less than that of the liquid, the weight of the liquid that would be displaced by the volume of the object will be greater than the weight of the object and the object will float. If the density of the object is more than the density of the liquid it would displace when submerged, the object will sink.
