Answer:Because mass and volume are independent, two objects with the same volume can have different masses. Therefore, the objects can have different densities. However,
if two objects have the same mass and volume, they will have the same density
.
How do you know if two objects have the same density?
Density equals the mass of the substance divided by its volume;
D = m/v
. Objects with the same volume but different mass have different densities.
Can objects have the same density?
Avg. Unlike the mass and volume that may be different for each specimen,
all objects made of the same material will have the same density
.
Can an object have the same volume and density?
The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). The mass of atoms, their size, and how they are arranged determine the density of a substance. … Objects with
the same volume but different mass have different densities
.
Can a liquid have the same density but different mass?
Two liquids that have the same volume don’t necessarily have the same density.
Density = mass/volume
, so they would only have the same density if they also have the same mass. Density is an intensive property, which means that it doesn’t depend on the amount of the substance present.
Does density stay same regardless size?
Why?
The density remains the same
because cutting the object in half will divide the mass & volume by the same amount. Also, the density of a substance remains the same no matter what size it is. All matter has its own unique density.
What objects are more dense?
Students should realize that if an
object weighs more than an equal volume of water
, it is more dense and will sink, and if it weighs less than an equal volume of water, it is less dense and will float.
Does an object with a density of 1 float in water?
In the case of water, an object with
a density less than 1 g/cm3 will float
. The closer its density is to 1 g/cm3, the more of it will sit below the water level. … This is equal to the force of gravity acting on a mass of water equal to the amount of water the object displaces when fully immersed.
What does density indicate?
Density is
a measure of mass per volume
. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).
How is density calculated?
The formula for density is
d = M/V
, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre.
What is density in liquid?
The density of a liquid is
a measure of how heavy it is for the amount measured
. If you weigh equal amounts or volumes of two different liquids, the liquid that weighs more is more dense. … If a liquid that is more dense than water is added to the surface of the water, it will sink.
What are the three properties of density?
- Mass of the Object. The mass of the object being measured for density is a part of the calculation. …
- Volume. Volume also decides the final density value. …
- The Calculation. Putting volume and mass together in a calculation defines density. …
- Water. …
- Ice.
Does shape change density?
Changing the shape does not change its mass or volume
, so density remains the same.
Why is density constant for each substance?
Liquids and solids
expand only slightly with increasing temperature
, and they compress only slightly with increasing pressure, so their densities are approximately constant under most ordinary conditions.
Will density change if volume changes?
Density is the amount of mass located in a specific volume. The density of an object
can change if either the mass or volume of the object is changed
.
