SCIENCE 101 FINAL EXAM BRAND
NEW OFFICIAL QUESTIONS WITH
ANSWERS.
Which Law of Thermodynamics addresses the direction that heat
flows? -correct answer -second
What is pseudoscience and how can you always recognize it? -
correct answer -idea being showcased as the truth; lack of
carefully thought out experiements
Other than familiarity, are there any advantages of the English
system of measurement? Explain. -correct answer -No. Under an
inch it becomes increasingly less precise.
What is a representation of an idea, object, or process used to
describe/explain something that cannot be experienced directly by
a scientist called? -correct answer -model
, Page | 2
What is any scientific idea or model that explains a natural
phenomenon called? -correct answer -concept
The kinetic molecular theory explains that the expansion of a solid
material with increases of temperature as basically the result of -
correct answer -molecules moving a little farther apart
Using the absolute temperature scale, the freezing point of water
is correctly written as -correct answer -273 K
The metric unit of heat called a calorie is
a. the specific of water
b. the energy needed to increase the temperature of 1 gram of
water 1 degree celsius
c. equivalent to a little over 4 joules of mechanical work
d. all of the above -correct answer -d. all of the above
The heat transfer that does not require matter is -correct answer -
radiation

Styrofoam is a good insulating material because -correct answer -
it contains tiny pockets of air
As a solid undergoes a phase change to a liquid state, it -correct
answer -absorbs heat while remaining at a constant temperature
Compared to cooler air, warm air can hold -correct answer -more
water vapor
If you double the mass of a cart while it is undergoing a constant
unbalanced force, the acceleration will be -correct answer -half as
much
Doubling the distance between the center of an orbiting satellite
and the center of Earth will result in what change in the
gravitational pull of Earth for the satellite? -correct answer -one-
fourth as much
If a ball swinging in a circle on a string is moved twice as fast, the
force on the string will be -correct answer -four times as great

How does an electron or proton acquire their charge? -correct
answer -The negative and positive description simply means that
these two properties are opposite, it does not mean that one
charge is better than the other. Charge is as fundamental to these
subatomic particles as gravitational attraction is to masses. You
cannot separate charge from an electron or proton. Like charges
produce a repulsive electric force as positive repels positive and
negative repels negative.
An object that acquires an excess of electrons becomes a(n) -
correct answer -negatively charged object
Which of the following is most likely to acquire an electrostatic
charge?
a. electric conductor
b. electric nonconductor
c. both are equally likely
d. none of the above are correct -correct answer -b. electric
nonconductor
A quantity of electric charge is measured in a unit called a(n) -
correct answer -coulomnb
