How can an object with more mass than another be the less dense?

Density has nothing to do with size. A given material will have the same density regardless of its size. A small object of a material with a high density can weigh as much as or more than a large object of a material with a low density.

The largest object is the densest object if it is made of the most parts

∙ 11y agodensity is defined as mass per volume. So even though the atmosphere may have more mass than a cat, the cat has a higher density because it has more mass/volume.

∙ 13y agoIf it takes up a lot more volume, then it will be less dense.
The atmosphere is far more massive than any person, however it is much less dense due to its shear size.

Is salt more or less dense than water?
Yes; that is why objects float more easily in salt water. yes, its true, the dead sea is so dense because of the salt that people can just float on top effortlessly The salt that is added dissolves into the water. The mass of the salt then adds to the mass of the water, increasing the density.
How does the density of a pure substance change?
The density of water changes when salt is added to it. Density is mass per volume. If salt is added to water, mass is increased but volume remains the same.
The bulk of the mass of the atom is concentrated in the small dense......?
The bulk of the mass of the atom is concenrated in the small, dense nucleus.
Why does the mass of alcohol decrease after heating?
The alcohol is cooked of and loses density in the liquid. Because the liquid becomes less dense, the mass goes down. (Unless you are talking about pure alcohol)
The density of an object depends on what?
mass and velocitythe object's speed and mass
How can you predict whether an object will float or sink in a fluid?
Measure the mass and volume of both to determine each's density (mass/volume). If the object is less dense; it will float, if it is mroe dense; it will sink.
When should an object float into a liqud?
An object will float when it has less density than the fluid or substance that it is placed in. The object floats upward due to buoyant forces. Similarly, objects will sink if they are dense than the fluid.
How would you verify the Archimedes principle for objects that are less dense than the liquid?
Two ways to do this: 1) Floating the less dense object on the more dense liquid. To verify the Archimedes principle you need to show that the mass of the liquid displaced by the less dense object is equal to the mass of the less dense object. To do this you need to have a way to determine the mass of the displaced liquid. If the liquid is in a container filled to the brim, then when you place the less dense object in it, the displaced liquid will spill out over the edges of the container. If you can collect and weight that liquid, then you can compare its weight to the weight of the less dense object - they should match. Alternatively, you can find a way to measure the volume of the displaced liquid and calculate the mass from the volume and density of the displaced liquid. 2) Immerse the object completely in the liquid and measure the force required to keep it submerged. This one is more complicated and difficult to execute and measure. The force required to keep the less dense object submerged should be the difference between the weight of the object (when it is not in the liquid) and the weight of the displaced liquid.
How can you predict if something will sink or float?
An object will sink if it weighs more than the water it pushes away, and an object will float if it weighs less than the water it pushes away. The Greek mathematician Archimedes discovered that the amount of water displaced by an object depends on the mass of that object. Mass is the amount of matter in a substance, and dense objects have more mass than less dense objects. Dense objects that do not displace much water will sink, while less dense objects that displace a lot of water will float.
How can you predict whether an object will sink or float?
The density of water is 1 g/cm cubed, and objects more dense that water will sink, while objects less dense than water will float. An object will sink if it weighs more than the water it pushes away, and an object will float if it weighs less than the water it pushes away. The Greek mathematician Archimedes discovered that the amount of water displaced by an object depends on the mass of that object. Mass is the amount of matter in a substance, and dense objects have more mass than less dense objects. Dense objects that do not displace much water will sink, while less dense objects that displace a lot of water will float.

What would a person do to make an object less dense without changing mass?
Since density is mass / volume, the other alternative is to increase the volume.
What law determines an object will float or sink in a fluid?
An object will float in a fluid if it is less dense than that fluid, because the mass of that object displaces less of the fluid than is the volume of the object. An object denser than that fluid would continue to displace the fluid until it met something either solid or more dense.
How does an object's density determine whether the object will sink or float in water?
the simple rule is that if your density is higher than the substance it will sink and if it is lower it will float density= mass divided by volume. Example:Mass 7.5g Volume:2cm3 so 7.5 Divided by 2= 3.75g/cm3 that is your density of object
How does a change in mass affect the movement of an object?
A change in mass would also change the level of density. If the level of mass in an object went down, it would make the object less dense. Anything that is less dense can move faster. Example: Think of someone cutting a pizza in half and keeping one half of it. A half pizza's mass is less than a whole pizza. You can move a half of a pizza easier than you can move a whole pizza, which is how it affects the movement.
Would two bigger things have a greater gravitational force than two smaller things?
Not necessarily, gravitational pull is dependant upon the mass of an object. A smaller object can have more mass than a bigger object (An extremely dense 1x1x1 cube has more gravitational pull than a less dense 3x3x3 cube that has less mass). Size has absolutely NOTHING to do with gravitational pull.
Why do some float and others sink?
Whether an object floats or sinks is a function of its relative density, to the medium in which it is placed. If the object is less dense, it floats, If it is more dense, it sinks. Density = Mass per unit Volume
