Correlation shows _____ not _____ - ANSWER: Positive & Negative....not cause &
effect
Which atom has the smallest mass? - ANSWER: Electrons = 0
What is an isotope? - ANSWER: Atoms of the same element that have different
numbers of neutrons (top #)
What are alpha particles represented by? - ANSWER: He or a
How do you find the amount of electrons in an isotope? - ANSWER: Subtract atomic
#(protons) from mass #(protons+neutrons)
Celcius scale (°C) - ANSWER: water freezes = 0
water boils = 100
Kelvin scale - ANSWER: water freezes= 273.15 K
water boils= 373.15 K
Ferenheit - ANSWER: water freezes = 32
water boils= 212
Conduction - ANSWER: Transfer of heat through direct contact (ex: touching a hot
pan)
Convection - ANSWER: Transfer of heat through fluid or gas (ex: putting hands over a
fire place or washing hands with hot water)
How is gas proportional to volume? - ANSWER: inversely proportional. (As pressure
increases, volume decreases)
How does the atomic radius change on the periodic table? - ANSWER: increases
moving down a group, decreases moving from left to right. (largest at the bottom left
corner)
What is an example of an ionic bond? - ANSWER: NaCl
exothermic reaction - ANSWER: releases energy (ex: hotter than its surroundings, fire
burning)
endothermic reaction - ANSWER: absorbs energy (ex: cooler than its surroundings,
heat melting ice)
, pH scale - ANSWER: # closer to 1 = Acidic
# closer to 14 = Basic
Vectors - ANSWER: quantities that have both a magnitude and a direction (ex:
velocity, acceleration, force)
scalar quantity - ANSWER: only magnitude, no direction (ex: speed)
Newton's First Law - ANSWER: An object at rest stays at rest and an object in motion
stays in motion with the same speed and in the same direction unless acted upon by
an unbalanced force.
Newton's Second Law - ANSWER: Force = mass x acceleration
Newton's Third Law - ANSWER: Every action has an equal and opposite reaction
Newton's Gravitational Law - ANSWER: The force of attraction between two objects
depends on mass and distance. As you increase distance the force decreases. (ex: if
distance doubles, force reduced to 1/4)
pressure - ANSWER: Force per unit area.
Period of a Simple Pendulum - ANSWER: depends on the length and rate of
acceleration due to gravity.
Colors lowest to highest frequency - ANSWER: ROYGBIV
amplitude of a wave - ANSWER: the wave's height from zero to the crest, LOUDNESS
pitch of wave - ANSWER: frequency, HIGHNESS OR LOWNESS OF A SOUND.
(determined by frequency)
Graham's Law - ANSWER: mass and diffusion rate
Where is most electronegativity found? - ANSWER: top right of periodic table
Heat is absorbed by a solid when melting.... - ANSWER: change in H is positive,
change in S is positive
Is freezing endothermic or exothermic? - ANSWER: exothermic
When animals take in more energy that is used over an extended period of time the
extra chemical energy is stored as... - ANSWER: Fat
What was the first enzyme in early life on earth? - ANSWER: RNA
