the volume of water that is pushed away by a sinking object
squared centimeter - (cm2)
metric area unit
area
length X width, amount of flat surface(base area), 2D (two dimensional) space
cubic centimeter- (cm3)
metric volume unit, submerged volume.
graduated cylinder
an instrument that measures the volume of a liquid in milliliters (ml)
milliliter (mL)
metric liquid unit
overflow container
an instrument that measures the volume of liquid in mL
volume
length x width x height, amount of space an object takes up, 3D space
submerge
below the surface of the liquid
submerged volume
amount of space occupied by the part of the object below the surface of the liquid , Length X width X depth
density
a relationship between an object's mass and its volume, the number of grams in one cubic centimeter Density = Mass / Volume Density unit is g/mL (liquid) or g/cm3 (solid object)
sinking
The object mass is larger than the objects volume. The object will sink when the density is more than the liquids density that the object is in.
floating
the object mass is smaller than the objects volume. The object will float when the density is less than the liquids density that the object is in.
subsurface
the object mass is the same as the objects volume. The object will sink and float when the density is the same as the liquids density that the object is in. Formulas for Density, mass and volume. When given two pieces of information use the following formulas.
D=M/V M= D x V V= M/D
density=
mass/volume
volume=
mass/density
mass=
density x volume
