1. The density of an object determines whether it will float or sink in another substance.
2. An object will float if it is less dense than the liquid it is placed in.
3. An object will sink if it is more dense than the liquid it is placed in.

How can you tell if an object will sink or float by comparing the weight of the object and the buoyant force?

If the buoyant force is greater than the object’s weight, the object will rise to the surface and float. If the buoyant force is less than the object’s weight, the object will sink. If the buoyant force equals the object’s weight, the object will remain suspended at that depth.

Does mass alone determine whether an object will float or sink explain Does volume alone determine whether an object will float or sink explain compare the mass and volume of each object What is true of the mass and volume of all the floating objects What is true?

Does mass alone determine whether an object will float or sink? No. Explain: There were objects that weighed way less than some objects that weighed a lot and still sunk. Also, some that weighed a lot more than others and floated.

Why do objects float or sink in liquids?

The object floats or sinks due to the buoyant force. When an object is immersed in a liquid it experiences an upward force known as Buoyant Force. The buoyant force (or upthrust) pulling upwards (which tends to push up the object).

What causes object to float?

An object floats when the weight force on the object is balanced by the upward push of the water on the object. If the weight force down is larger than the upward push of the water on the object then the object will sink. If the reverse is true then the object will rise – rising is the opposite of sinking.

What is Archimedes Principle in simple terms?

Archimedes’ principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid. This is a first condition of equilibrium.

What is Archimedes Principle and how can it be verified?

Summary. When a body is partially or wholly immersed in a fluid, it experiences an upthrust. Archimedes’ principle states that “When a body is immersed completely or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by the body.” This can be verified experimentally.

What is Archimedes principle and its application?

Archimedes’ principle states that when a body is immersed fully or partially in a fluid, it experiences an upward thrust equal to the weight of the fluid displaced by it. The applications of Archimedes’ principle are: (i) Archimedes’ principle is used in designing ships and submarines.

What does buoyant force depend on?

Notice how the buoyant force only depends on the density of the fluid ρ in which the object is submerged, the acceleration due to gravity g, and the volume of the displaced fluid V f V_f Vf​V, start subscript, f, end subscript. Surprisingly the buoyant force doesn’t depend on the overall depth of the object submerged.

What does upthrust depend on?

The magnitude of upthrust on a body due to a liquid depends on: Volume of the body submerged in the liquid (or fluid). Density of the liquid (or fluid) in which the body is submerged.

Does upthrust depend on mass?

This is due to upthrust. The effect of upthrust is that weight of the body immersed in a liquid appears to be less than its actual weight. There are two factors on which upthrust depends – Volume of the body and Density of the Liquid. Larger the volume of body submerged in liquid, greater is the upthrust.

Does upthrust depend on acceleration?

Upthrust does not depends up on the acceleration due to gravity.

What is maximum upthrust?

A body will experience maximum upthrust when it is completely immersed in. As the upthrust is directly proportional to the density of the liquid in which the body is immersed so here the upthrust due to honey will be maximum as the honey among the other has maximum density .

What are characteristics of upthrust?

Explanation: The upthrust has the following three characteristic properties : (i) Larger the volume of body submerged in fluid, greater is the upthrust. (ii) More the density of fluid, greater is the upthrust.

What is SI unit of upthrust?

The unit of buoyant force is Newton (represented by N). Thus, the S.I. The unit of upthrust force is also Newton (N).

How do you calculate upthrust?

Upthrust is the force exerted by a fluid on an object in upwards direction. That’s why up-thrust acts against the weight of an object. We know that Upthrust (U) = weight of the liquid displaced by the submerged part of the body. So U=mg , where m is mass of the body and g is the acceleration due to gravity.

What is upthrust Class 9?

Upthrust is the upward force acting on a body when it is partially or fully immersed in a liquid, it is also referred to as buoyant force.

What is the formula for calculating buoyancy?

In general terms, this buoyancy force can be calculated with the equation Fb = Vs × D × g, where Fb is the buoyancy force that is acting on the object, Vs is the submerged volume of the object, D is the density of the fluid the object is submerged in, and g is the force of gravity.

What is the relation between upthrust and density?

density is one factor affecting upthrust (buoyant force). if the density of the substance is more than the density of the fluid, then the upthrust will be less and thus the substance sink. if the density of the substance is less than the density of the fluid, then the upthrust will be more and thus the substance float.

What is the relation between weight and density?

The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. Density is mass/volume.

What is the relationship between the density of the liquid?

Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter. The density of a substance is the same regardless of the size of the sample.

How is upthrust related to volume?

How is the upthrust related to the volume of the body submerged in a liquid? Upthrust force acting on a submerged body is equal the weight of the liquid displaced whose volume is equal to volume of the submerged body.

What is the principle of floatation?

When any boat displaces a weight of water equal to its own weight, it floats. This is often called the “principle of flotation”: A floating object displaces a weight of fluid equal to its own weight.

How is upthrust related to acceleration due to gravity?

Upthrust = weight of the liquid displaced by the submerged part of the body Upthrust = mass of liquid displaced x Acceleration due to gravity Upthrust = volume of liquid displaced x density of liquid displaced x Acceleration due to gravity,Since volume of solid immersed is equal to the volume of the liquid displaced.

What do you know about Archimedes principle in chemistry?

Archimedes’ Principle says that the apparent weight of an object immersed in a liquid decreases by an amount equal to the weight of the volume of the liquid that it displaces. Knowing the mass and the volume of an object allows us to calculate the density.
