**Volume** is measured
in cubic units. (cubic cm, cubic m, cm^{3}, mm^{3}, etc)

**Volume** is the amount of space the object takes up.

A cube has width, base, and height (V = w*b*h)

A cylinder’s volume is calculated (V=πr^{2}h)

A sphere’s volume is calculated V=4/3 πr^{3})

The object
submerged in a fluid will **displace** an amount of fluid that is equal to the volume of the object.

*Displace**: to move out of the way and put something else in its place.*

All objects
have the property of **density**.

**Density** is the relationship between mass and **volume**.

d=m/v v=m/d m=dv

1cm^{3
}= 1 cc = 1 mL (1cubic centimeter = 1 milliliter)

The density of an element is unique.

By
computing the density of a sample, you can determine what it is.

**The density of water is 1.0 Kg/L.**

** ****An object with a density less than the fluid in which it rests will FLOAT.**

Example : An object with a density less than 1.0 Kg/L will FLOAT in water.

**An object with a density greater than the fluid in which it rests will SINK**

Example: An object with a density greater than 1.0 Kg/L will SINK in water.

**An object with a density that is equal to the fluid in which it rests will HOVER.**

Example: An object with a density that is equal to 1.0 Kg/L will HOVER in water.

**Altering
volume will alter density.**

Example: Large
naval ships are made from metal, that if it were in a large lump, would sink.

Increasing the volume without
increasing mass causes a decrease in density.
