The density of a substance
is the same regardless of the size of the sample
.
Does the density of a substance change as the substance changes state?
The density of
a material does not change when
we change the volume of an object.
Does a density of a substance change?
The density of an object can change if either the mass or volume of the object is changed
. Fluids, such as water, have a certain density. If an object is more dense than water, it will sink; if it is less dense than water, it will float.
Does the density of a substance ever change Why or why not?
Does size (or amount) affect density? … However, the density does not change. This is
because the mass and volume increase at the same rate/proportion
! Even though there is more molasses (mass) in test tube A, the molasses also takes up more space (volume).
Will the density of a substance change if more of the substance is present?
Extensive properties, such as mass and volume, depend on the amount of matter
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.
What are the factors affecting density of matter?
- Atomic weight of the element or the molecular weight of the compound .
- The distance between atoms ( Interatomic distances ) or molecules ( Intermolecular spaces ) .
Why does the density never change?
Does size (or amount) affect density? … However, the density does not change. This is

Can two substances have the same density?
They do not vary from one sample of the same substance to another. … However,
it is possible for two different substances to have the same density
.
Can two objects have the same density?
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
.
Which is the highest density substance among?
- Gold has the highest density among the given elements.
- Density of Gold= 19.32 g/cc.
- The density, of a substance, is its mass per unit volume.
- Osmium is the densest element in the periodic table.
- Density of osmium= 22.6 g/cc.
Is density intensive or extensive?
Density is an
intensive property
of matter that illustrates how much mass a substance has in a given amount of volume.
What is the density of pure water?
A common unit of measurement for water’s density is gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm
3
). Actually, the exact density of water is not really 1 g/ml, but rather a bit less (very, very little less), at
0.9998395 g/ml at 4.0° Celsius
(39.2° Fahrenheit).
Where is density used in real life?
In
an oil spill in the ocean
, the oil rises to the top because it is less dense than water, creating an oil slick on the surface of the ocean. A Styrofoam cup is less dense than a ceramic cup, so the Styrofoam cup will float in water and the ceramic cup will sink.
Does density affect weight?
Density is an intensive physical property whereas weight is an extensive property. Density changes when
the pressure and temperature of an object changes
, whereas the weight changes when the mass of an object and gravity changes. … Gravity does not affect density whereas on the other hand gravity directly affects weight.
Why is density used to identify a material?
Density
indicates how much of a substance occupies a specific volume at a defined temperature and pressure
. The density of a substance can be used to define the substance. Water is unusual because when water freezes, its solid form (ice) is less dense than liquid water, and thus floats on top of liquid water.
