Sinking and floating?
An object sinks if it is denser than the liquid it is immersed in, causing it to displace an amount of liquid that weighs less than the object itself. Conversely, an object floats if it is less dense than the liquid it is placed in, allowing it to displace a sufficient amount of liquid to support its weight. Archimedes' principle explains this phenomenon.
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.
What does the scientific word buoyancy mean?
Buoyancy is the ability of an object to float in a liquid or gas. It is determined by the object's density compared to the density of the surrounding fluid. If the object is less dense than the fluid, it will float; if it is more dense, it will sink.
Why is it that you do not sink even if it is 75 percent water and 25 percent land?
Appropriate answer:Your body's density is less than 1, while the density of water is 1. There's a physics law that states if an object of lesser density is suspended in a higher dense liquid, the object will float. If they are of equal density, the object will still float. However, if the object is denser than the liquid, the object will sink.But if you mean if we don't sink even though the world's surface is 75% covered with water, guess what? You're living on land, not water.Have a laugh:Of course the Earth will not sink! It's suspended in space!
What does it mean to compare the density of an object to that of it in pieces?
It means: * Calculate the density of an object * Calculate the density of its pieces * Compare
How an object floats in liquid?
An object floats in liquid when the weight of the liquid displaced is equal to or greater than the weight of the object. This creates an upward buoyant force that supports the object's weight, allowing it to float. Objects that are less dense than the liquid they are in will float, while objects more dense will sink.
Does density of an object change with altitude?
I am assuming that you mean mass of an object. The answer is no, it does not change. Mass (Density) stays the same wherever the object is, only its weight will change if the force of gravity is different.
When an object is heavier does that mean it is more dense than other objects?
Not necessarily. The weight of an object is determined by its mass and the force of gravity acting on it, while density is a measure of how much mass is contained in a given volume. A heavier object can be less dense if it takes up more volume, or it can be more dense if it is compact and takes up less volume.
What happens to the density of a substance as it changes from a liquid to a gas?
I assume you mean a solid that has the same density as a liquid that it is submerged in. If they have the same density, then when the solid is in the liquid, there is exactly zero net force acting on it (weight of solid object is perfectly balanced by bouyant force), so the solid object will just "sit there," assuming there are no other outside forces acting on it (ex. currents, etc.). If the object is dropped into the liquid, for example, it will move deeper into the liquid (because it has downward momentum from the drop) until resistance from the liquid stops its motion, at which point it should remain stationary.
What does upthrust mean in science?
In science, upthrust refers to the upward force exerted on an object immersed in a fluid (liquid or gas). It is a type of buoyant force that counteracts the weight of the object, causing it to float or rise. Upthrust is dependent on the density of the fluid and the volume of the object displaced.
What happens if an object is more dense?
Density tells us how much matter is packed into a measured volume. That means:Density=Mass______VolumeSo that means the more dense an object is, the more particles in them are compressed together (heavier).:)
What is the amount of mass per unit volume in an object mean?
The ratio mass/volume is called density.
