States of Matter
liquid to gas
evaporation
center of an atom (protons + neutrons)
nucleus
method of displaying data, often used to show information about percentages or parts of a whole, that divides a circle into sectors
circle or pie graph
changing the order of addends does not change their sum; a + b = b + a.
commutative property of addition
your prediction about how the experiment will turn out before you know the results
hypothesis
gas to liquid
condensation
protons, neutrons, electrons
subatomic particles
the vertical number line of a coordinate plane or graph
y-axis
the grouping of factors does not affect their product; a x (b x c) = (a x b) x c
associative property of multiplication
a statement that shows two ratios are equal
proportion
solid to gas (skip liquid)
sublimation
elements in the same group that also share similar properties
family
method of displaying data that involves splitting the data into four groups of equal size
box-and-whisker plot
the sum of any number and 0 is equal to the initial number; a + 0 = a
identity property of addition
a kind of friction caused by air pushing against a moving object (how parachutes work)
air resistance
gas to solid (skip liquid)
deposition
electrons on the outer-most shell of an atom
valence electrons
method of graphing a collection of numbers by placing the inital digits in one column to the left and the remaining digits to the right
stem-and-leaf plot
using operations that "undo" each other; addition and subtraction, multiplication and division, raising to powers and finding roots
inverse property (of addition and subtraction)
a way of writing a number as the sum of the products of the digits and the place values of the digits
expanded notation
how tightly packed matter is, measured by mass divided by volume
density
average mass of protons and neutrons
atomic mass
measures the spread of the middle of the data; found by subtracting the upper quartile by the lower quartile
interquartile range (IQR)
multiplicative identity
1
the second push or pull (force) that responds to the action force HINT: Newton's 3rd Law
reaction force
