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.

What is a floater in a sinker in terms of density?

A floater is an object that has a lower density than the fluid it is in, allowing it to remain on the surface or float. In contrast, a sinker has a higher density than the fluid, causing it to sink. This principle is governed by Archimedes' principle, which states that an object will float or sink based on the relationship between its density and the density of the fluid.


What is density in everyday terms?

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.


Why you are able to float easily using the terms density and buoyant force?

When the density of a object is less than that of the surrounding fluid, the buoyant force is great enough to move it up.


Explain in terms of density and Charles's law why heating the air allows a hot-air balloon to float?

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.


In terms of buoyancy how does a life jacket save your life?

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.


Can scandium float?

Scandium is a metallic element with a density of about 2.985 grams per cubic centimeter, which is significantly higher than that of water (1 gram per cubic centimeter). Therefore, scandium cannot float in water; it would sink. Its density makes it a solid metal that behaves like most metals in terms of buoyancy.


What conditions must be met in terms of density of a body for it to float submerged in water?

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.


Why do hings float better in salt water than freash water?

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.


Why is there no heat transfer by convection in solids?

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.
