Objects that are less dense than the environment in which they are immersed will float, unless they are tethered.

∙ 7y agoA sinking object can have any mass. It can also have any volume. Furthermore, it would be incorrect to suggest that the density of the sinking object must be grater than that of the fluid. Steel is much denser than water but ships made of steel can float. It is neither the mass nor the density but the mass of the fluid that is displaced by the object when submerged.
Just to add a further complication. A steel needle can be made to float on water as follows: put a needle on a piece of blotting paper and very gently lower them onto the surface of water. The paper will absorb water and sink from under the needle. The needle should float - not because of the buoyancy of water but because of its surface tension!

∙ 14y agoIt's density, not mass, that affects whether a solid object floats. Objects with a density of less than 1 will float, if density is greater than 1, they will sink.

∙ 11y agoan object sinks in water then its mass is greater than the mass of the volume of water that the objects displays
Wiki User
∙ 9y agoFor an object to sink, its density (mass / volume) must be greater than the density of the liquid or gas in which it is placed.
Wiki User
∙ 9y agoIf an object floats, it means that its density - mass divided by volume - is less than the density of the liquid on which it floats.

∙ 13y agoThe mass of any sinking object, when divided by its volume, results in a number
that is greater than the density of the fluid in which the object is sinking.

A balance is used to measure mass true or false?
True, the most common method is to use a balance
Is this statement True or False The amount of matter in an object is it's weight?
False It should read: The amount of matter in an object is its mass (not weight)
What must be true about the weight of an object and the buoyant force acting on the object in order for that object to float?
They must be equal. When forces are balanced, there is no acceleration, and the object will neither rise nor sink.
What is the definition of actual mass?
The actual mass number is the total number of neutrons and protons in the nucleus of an atom. Atoms commonly have varying numbers of neutrons in the same element, these variants are referred to as isotopes.
Why does the density of an object never change?
1 I'm not sure that this is true-- at least without some qualifications. If an object's shape is changed in such a way that it will enclose one or more pockets of air, some other substance, or even vacuum, the object's over-all density may change. If no pockets are formed, then the density probably is not changed 2 Density is the ratio of mass to volume.
What is true about the mass and volume of all floating objects?
The volume of liquid displaced has the same mass as the floating object.
If an object floats the volume of the displaced water is equal to the volume of the portion of the object that's underwater true or false?
It's true that the volume of displaced water of a floating object equalst the portion of that object that is underwater.
Is density calculated by dividing the mass of an object by its volume true or false?
true
Is it true or false Density is calculated by dividing the mass of an object by its volume.?
true
Is it true that Density is calculated by dividing the mass of an object by its volume?
Yes
How do you find the volume of a floating object?
Exactly the same as for a non-floating object. Finding the volume of a shape does not vary, (i.e it's always something along the lines of height*width*depth, or area of base *height. "Table" or "surface" is irrelevant, since if it not a variable in the formula). This is true whether the object is floating or not.
True or false an object buoyant force and weight arent the same thing?
Yes they are different things. Buoyant force is always upward. Weight is always downward. Also ... -- Weight depends on the object's mass. -- Buoyant force depends on its volume, and on what it's floating in.
Will an object float if the volume is bigger than its mass?
If these measurements are made in cubic cemtimeters (volume) and grams (mass) this is true. But, if mass is from the english system, (not really pounds, it is slugs, but who knows what a slug is?) and the volume is cubic feet, this is not true.
Is it true that you can determine the kinetic energy of an object if you know mass and volume?
No, that's not true. Look at the formula for kinetic energy. You need mass and speed.
If an object floats the volume of displaced water is equal to the volume of what?
Look at the LAST WORD of the question, they switch it sometimes if it is: Underwater than it is TRUE, If it's Surface of the water than it is FALSE ~
What is true about the mass and volume of all sinking object?
If an object sinks in water, then its mass is greater than the mass of the volume of water that the object displaces. (That could be equal to or greater than the object's actual volume ... a drinking glass displaces more water than the volume of glass in it until the water washes over its rim. A canoe, a bass-boat, and a ship are designed to displace more water than their actual volume.)
To find the mass of a rectangular object you multiply the object's length width and height. True or false?
False on two counts. A rectangular shape is 2-dimensional and so can have no mass. If it is rectangular but has length, width and height then it is a cuboid object. Then, multiplying the length width and height will give the volume, not the mass.
