What does density depend on? The density of an object is the
mass of the object compared to its volume
. The equation for density is: Density = mass/volume or D = m/v. Each substance has its own characteristic density because of the size, mass, and arrangement of its atoms or molecules.
What factors does density depend on?
Answer: Density means Mass per unit volume so density depends upon the
mass(m) and volume(v) of the substances
.
Does density depend on mass or volume?
What does density not depend on?
Does density depend on amount of substance?
What are the 3 main factors that affect density?
The
size, mass, and arrangement of atoms
affect the density of a substance.
What 2 factors affect density?
- Temperature: Change in temperature causes a change in the density of the substance.
- Change of state: If the state of a substance changes, the density changes. …
- Compression: If a body is subjected to compresssion, the density of the body will increase because volume for the same mass is reduced.
Is density dependent or independent?
Density dependent factors are those that regulate the growth of a population depending on its density while density independent factors are those that regulate population growth without depending on its density.
Does density depend on pressure?
Pressure and Density Relationship
When pressure increases, density increases
. When the pressure decreases, density decreases.
Does density increase with mass?
We know, from above, that when the volume is constant, the density is directly proportional to the mass, this means that
at constant volume, the density will increase as mass increases
.
Does Weight Affect density?
The density of an object is directly proportional to its mass and inversely proportional to its volume. On the other hand, weight is directly proportional to mass and independent of volume. Therefore,
the density of a substance increases with its weight
, provided that the volume of the object remains constant.
Does density change with state of matter?
When a material changes its phase or state of matter, its volume and thus its density usually changes
. Although pressure can influence the change of state of a material, temperature is the main factor.
Does density depend on temperature?
The warmer the water, the more space it takes up, and the lower its density
. When comparing two samples of water with the same salinity, or mass, the water sample with the higher temperature will have a greater volume, and it will therefore be less dense.
What factors affect the density of a liquid?
Answer: There are two main factors which affect the density of water, namely,
Temperature and Purity
. The density of pure water varies with temperature and attains its maximum value at a temperature of 4^{0}C. Impure water density increases with respect to impurity.
Does gravity affect density?
How does gravity affect density?
The gravity of the body will work to increase its density
. If we think of gravity as a force then to achieve equilibrium something needs to counteract the force of gravity, usually electromagnetic repulsion caused by neighboring electron shells.
Does size affect density?
In other words, the size or amount of a material/substance
does not affect its density
.
What is density-dependent examples?
How do you know if something is density-dependent?
Which is a density independent factor?
Why does pressure increase density?
The higher the density of an object that is exerting the pressure, the higher the pressure on the object on which the pressure is being exerted. It follows that the higher the pressure exerted on an object, the higher will be its density
because the object will be compressed
.
Does pressure affect density of water?
Does water change density under pressure?
if the fluid is hot water, saturated, the density is higher by given higher pressure
. fluid can either be gas or liquid. the density of a fluid is inversely proportional to its pressure hence, as pressure is increased, a decrease in density is observed, mass etc. being kept constant.
What causes density to increase or decrease?
Do heavier objects have higher density?
If something is heavy for its size, it has a high density
. If an object is light for its size it has a low density.
What two ways will increase density?
In general, density can be changed by
changing either the pressure or the temperature
. Increasing the pressure always increases the density of a material. Increasing the temperature generally decreases the density, but there are notable exceptions to this generalization.
What makes an object more dense?
The more mass an object contains in a given space
, the more dense it is. It is important to remember, though, that this relationship is not just about how closely packed together the atoms of an element or the molecules of a compound are. Density is also affected by the atomic mass of an element or compound.
Do smaller objects have more density?
Is denser lighter or heavier?
Density tells scientists how “heavy” a substance is.
If a substance has a higher density, it is heavier
. Likewise a lighter density means it is much lighter.
What makes dense?
Does density change with form?
density, mass of a unit volume of a material substance. 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.
Does density increase with volume?
If volume increases without an increase in mass, then the density decreases
(Fig. 2.2 A to 2.2 C). Adding additional matter to the same volume also increases density, even if the matter added is a different type of matter (Fig.
Is density proportional to mass?
Note that density is
directly proportional to the mass
(or weight) and indirectly proportional to the volume: If volume stays the same as mass increases, the density will increase by the same factor. If volume stays the same as mass decreases, the density will decrease by the same factor.
