Density (Mass, Volume, Density)

matter

anything that has mass and takes up space

mass

how much matter an object is made up of

volume

the amount of space an object takes up

graduated cylinder

an instrument used to measure the volume of an object

water displacement

a method to find the volume of an irregular-shaped object using water and a graduated cylinder

triple beam balance

a type of scale used to measure the mass of objects

V= l x w x h

the formula used to find the volume of a cube or rectangular prism (regular shaped solid object)

D = m/v

the formula to find the density of an object
Density = mass divided by volume

density

how much mass an object has in a given amount of volume/space

Solid

matter that has molecules very tightly packed together

Liquid

matter that has molecules that have some space between them to move

Gas

matter that has molecules that are very spread out

gram

the unit used to measure the MASS of objects

cm3

the unit used to measure the VOLUME of SOLID objects

mL

the unit of measurement used in to measure the VOLUME of LIQUIDS (like water by itself)

g/cm3

the unit of measurement for the DENSITY of a SOLID object

g/mL

the unit of measurement for the DENSITY of a LIQUID

If two liquids are poured into a container. They form 2 layers. Liquid A is blue and sinks to the bottom while Liquid B is orange and stays on top. Which liquid is more dense? Liquid A or Liquid B?

Liquid A

What do we know about an object's density if it floats on water?

The object is less dense than water.

What measurement describes the amount of space an object occupies?

volume

What measurement is the amount of matter in an object?

mass

over flow cup

instrument used to measure volume of an object

ruler

a tool used to measure volume of a flat object, LXWXH

Formula to find volume

V=M/D

Formula to find mass

M=DV
