What Two Things Does Density Depend On

What Two Things Does Density Depend On?

Density depends on both mass (amount of matter) and volume (amount of space). Remember mass is how much matter is in an object and you use a scale or balance to find mass. Volume is the amount of space that an object occupies. Since density includes volume fill in the review on finding volume.

What are 2 things does density depend on?

Density (d) depends upon the mass (m) and volume (v) of a substance. The mass depends upon the amount of matter in a substance whereas volume is the amount of space that a substance takes up.

What does the density of an object depend on?

Density Mass & Volume

Size-wise both suitcases look the same but their density depends on the relationship between their mass and volume. Mass is the amount of matter in an object. Volume is the amount of space that an object takes up in three dimensions.

Does density depend on its volume?

Density is the ratio of the mass of an object to its volume. Density is an intensive property meaning that it does not depend on the amount of material present in the sample.

Why does density depend on volume?

Volume is the three-dimensional space enclosed by the closed surface. Density is mass per unit volume. The relation between density and volume is directly proportional. That is any change in volume will result in the change in its density and vise-versa.

What causes density?

The density of a material varies with temperature and pressure. … Increasing the pressure on an object decreases the volume of the object and thus increases its density. Increasing the temperature of a substance (with a few exceptions) decreases its density by increasing its volume.

Does density depend on area?

Current density depends on amount of current Area through which the current flows and the angle between area and direction of current.It is denoted by j.

How does density depend on mass and volume?

Density (d) depends upon the mass (m) and volume (v) of a substance. The mass depends upon the amount of matter in a substance whereas volume is the amount of space that a substance takes up. Mathematically density is equal to a ratio where d = m/v.

What causes density to change?

Density changes with temperature because volume changes with temperature. Density is mass divided by volume. As you heat something up the volume usually increases because the faster moving molecules are further apart. Since volume is in the denominator increasing the volume decreases the density.

How does density affect the mass of an object?

Density = Mass/Volume which means that density is how heavy an object is compared to its size – so how closely its molecules are “packed” together. … Density = Mass/Volume also means that the larger the volume of an object compared to its mass the less dense it is.

Does density depend on mass CER?

Density of an object is dependent on an object’s mass and volume. i.e. it is the ratio of mass and volume.

What does density have to do with objects that float?

Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water and if it is less dense than water it will float.

What are the two quantities involved in the determination of density explain?

Density is a derived quantity – we measure two other quantities (mass and volume) and then calculate density.

Does density increase with mass?

If the volume stays the same then an increase in mass will cause an increase in density. However an increase in mass along with an increase in volume can give rise to no increase in density which would describe an intensive property.

Does the density of a substance depend on how much of the substance you have?

Because the density of a substance does not depend on the amount of substance present density is an “intensive property”. To measure the density of a sample of material both the mass and volume of the sample must be determined.

Why does density not change with 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.

How does the density of a material depend on its structure?

The density of an object or quantity of matter is its mass divided by its volume. … In some cases materials made of atoms with a lower atomic weight have a greater density than those with a higher atomic weight due to the atoms being more tightly packed. This is especially true for solids.

Can two substances have the same density?

So Pure materials they can not have same densities. (Assuming they are not isotopes of each other.) But mixtures compounds or different phases can have same densities. That being said I would have to say that elements will all have individual weights and densities but compounds can be made up in any number of ways.

What is density related to?

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 related to area?

Area or surface density is the amount of a quantity (often mass) per unit of area. Density=Quantity/Area.

Does density depend on pressure?

Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases with temperature constant density increases. Conversely when temperature increases with pressure constant density decreases.

Does current density depend on conductivity?

Conductivity relates current density to the applied field directly without requiring one to grapple separately with the issues of applied force and charge mobility.

How does density affect gravity?

Objects that are denser have a greater concentration of mass thus creating a larger gravitational pull than a same-sized object with lower density—i.e. a cubic foot of solid rock will exert a larger pull on its surroundings than a cubic foot of ocean.

Why does density decrease when volume increases?

As you heat something up the volume usually increases because the faster moving molecules are further apart. Since volume is in the denominator increasing the volume decreases the density.

What are the factors that affect density determination?

The factors that affect the density
  • Atomic weight of the element or the molecular weight of the compound .
  • The distance between atoms ( Interatomic distances ) or molecules ( Intermolecular spaces ) .

What affects water density?

Water density changes with temperature and salinity. Density is measured as mass (g) per unit of volume (cm³). Water is densest at 3.98°C and is least dense at 0°C (freezing point). Water density changes with temperature and salinity.

Why does density increase when mass increases?

We know that density is given by mass divided by volume. According to this formula the density is directly proportional to the mass when the volume is constant and inversely proportional to the volume when mass is constant. … Thus at constant volume the mass of a substance increases when the density increases.

What makes something 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.

How does the density of an object depends on the temperature and the mass of the object?

What makes density increase? The density of a material varies with temperature and pressure. Increasing the pressure on an object decreases the volume of the object and thus increases its density. Increasing the temperature of a substance (with a few exceptions) decreases its density by increasing its volume.

Does the density of a material depend on the size or shape of the object of which it is made?

Explanation: Density is an intensive property. This means that regardless of the object’s shape size or quantity the density of that substance will always be the same. Even if you cut the object into a million pieces they would still each have the same density.

Does the density of a liquid depends on the temperature?

Temperature Affects Density

The density of water can also be affected by temperature. When the same amount of water is heated or cooled its density changes. When the water is heated it expands increasing in volume.

Does composition affect density?

The density of liquids and gases is controlled by: chemical composition (including soluble components) temperature and pressure (density increases with increasing pressure and decreasing temperature).

How does an object floating or sinking ability in water depends on density?

The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.

What makes things sink or float?

An object floats when the weight force on the object is balanced by the upward push of the water on the object. … If the weight force down is larger than the upward push of the water on the object then the object will sink. If the reverse is true then the object will rise – rising is the opposite of sinking.
