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.
Is Density of helium balloon is greater or less than air?
The density of helium is less than that of air. Due to this reason, balloons filled with helium will float in air.
What is volume weight and density?
volume is how much space is in an object (an object with more volume would be bigger) weight is how heavy an object feels due to gravity (an object with more weight would be harder to lift) density is how much matter is in an amount of space (an object with more density would weigh as much as an object with less density but in a smaller space/volume)
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 does density affect floating and sinking objects?
D=m/v if an object is more dense than water it will sink. If it is less dense then it will float. The SI units for density are kilograms per cubic meter, giving water a density of 1 kg/m^3. If the density of a substance is less than 1, it will float in water.
Why do some solids sink and some solids float?
Anything heavier than water sinks; anything lighter than water floats. Or, another way to say it: anything with a higher density than water (water weighs about a gram per cubic centimeter), or a higher specific gravity than water, sinks. If the object weighs less than the weight of water that it displaces, then it floats.
Can you use volume alone to predict whether an object will sink or float?
Calculate the density (mass divided by volume) of your object. If the density is less than that of water - which has a density of about 1000 kg per cubic meter - then it will float; if the density of your object is more, it will sink.
What do you notice about the density of floating objects?
Usually the density of floating object will be less than that of the liquid in which it is floating. But exception is that ship made up of iron will float in less dense water. Becasue a large amount of water will be displaced due to the specific construction of the ship. The weight of the displaced water will be more than the floating ship.
Which force determines whether or not an object will float?
This is archemedies principle. This is a balance between the force on the water displaced by gravity compared to the force on the floating object due to gravity. That is if the average density of the object that whishes to float is less then water then it will float. If it is greater then it will sink.For a boat the average density is the average of the density of the hull and the air inside the hull.
Why do some object sink when placed in water?
That Depends upon a principle Buoyancy.That means that the object placed in water should have density (particles per unit volume) less than that of water to float or else it will sink. Like when we will put a plastic block in water it will sink but when a bottle made of same plastic block is put in water it floats because it have comparatively lower density to the block due to air.
How does the density around a partial positive electron atom compare to the density of a partial negative?
The density around a partial positive is typically less than the density around a partial negative. This is due to the ionization of the ion.
Is an object that floats a chemical change?
no, it is due to density, a physical property
