Questions With 100% Verified Answers
Correlation shows _____ not _____ - answerPositive & Negative....not cause & effect
Which atom has the smallest mass? - answerElectrons = 0
What is an isotope? - answerAtoms of the same element that have different numbers ...
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
