AND CORRECT DETAILED ANSWERS - VERIFIED ANSWERS ALREADY
GRADED A+ NEW GUARANTEED
Heat - CORRECT ANSWER A form of energy transfer without macroscopic motion due
to a difference in temperature.
Work - CORRECT ANSWER energy used to impart motion, product of distance moved
times the magnitude of force opposing the motion
- W = f*l
- dW = Fdl
- power = rate of work: W = Fv
- W>0 for work done on system
- W<0 for work done BY system
Kinetic energy - CORRECT ANSWER Stored energy that takes the form of motion
- KE = 1/2*M*V^2
Potential Energy - CORRECT ANSWER Stored energy associated with an object's
position in a force field due to gravitational and/or electromagnetic forces
- PE = Ugh
Internal Energy - CORRECT ANSWER Energy stored within matter on a microscopic
level (individual molecules).
- found by measuring energy added/removed for a particular change in state relative to a
reference state
Enthalpy - CORRECT ANSWER
Entropy - CORRECT ANSWER the degree of disorder or randomness in a system. a
quantitative way of describing how energy disperses or spreads out in a system. The
amount of energy unavailable to do work.
Availability - CORRECT ANSWER maximum energy that is able to be converted into
useful work obtainable as a system moves to equilibrium
Open System - CORRECT ANSWER has both matter and energy entering and/or
leaving the system
Closed System - CORRECT ANSWER no matter entering/leaving system, but energy
transfer can still occur
- ex: non insulated coffee cup
,adiabatic - CORRECT ANSWER no heat entering or leaving system
isothermal - CORRECT ANSWER constant temperature throughout the system
steady state - CORRECT ANSWER when all properties of the system are constant with
respect to time
equilibrium - CORRECT ANSWER no driving force for any change to its state
properties
- can be at steady state but not equilibrium. temperature at 3 diff locations are different
but the 3 temperatures separately are constant
first law of thermodynamics - CORRECT ANSWER energy is a conserved quantity. can
be converted from one from to another, transferred from one location to another, but not
created nor destroyed.
- three forms of store energy: kinetic, potential, internal
- two forms of transfer energy: heat and work
Force - CORRECT ANSWER F = ma
Shaft Work - CORRECT ANSWER work done by or on a rotating shaft such as
turbines, compressors, pumps, rather than linear motion. transmits rotational energy.
- W = fl, but l this time is revolutions
reversible process - CORRECT ANSWER idealized process
system remains in thermodynamic equilibrium at every point in process. no heat losses or
frictiion
- ex: isothermal expansion
- no entropy increase, stays same
irreversible process - CORRECT ANSWER natural process
cannot be undone or reversed without leaving a net change in the system or surroundings
involves friction, heat loss, turbulence etc
generation of entropy
- free expansion of gas into a vacuum
State function - CORRECT ANSWER properties that depend only on the current state of
the system: internal energy, enthalpy, entropy, pressure, temp
path function - CORRECT ANSWER depends on the specific path taken during a
process: work and heat
flow work - CORRECT ANSWER work required to push a fluid into or out of a control
volume, needed to move fluid through a system
- W flow = P*V
,Expansion/Contraction Work - CORRECT ANSWER work done during the expansion
or compression of a gas
second law of thermodynamics - CORRECT ANSWER The total entropy of an isolated
system can never decrease over time.

How did Woodrow Wilson's new freedom platform during the 1912 campaign differ from
that of that Theodore Roosevelt's new nationalism platform - CORRECT ANSWER
Wilson promised to preserve free economic competition
What cause the women suffrage campaign to split into two Groups - CORRECT
ANSWER Alice Paul's aggressive strategy clashed with NAWSA's strategy
How did world war 1 affect the cause of women's suffrage - CORRECT ANSWER It
gave women the opportunity to work in traditionally male dominated positions
Scientific progressives believed that reform of society should - CORRECT ANSWER Be
led by experts
President Roosevelt's progressive record includes all the following except - CORRECT
ANSWER Establishment of the federal reserve system
Progressivism was halted by - CORRECT ANSWER WW1
Which was the major contributor to Woodrow Wilson winning the presidency in 1912 -
CORRECT ANSWER Splitting the republican vote
Coverage D - CORRECT ANSWER This pays for the additional costs of living away
from home if a house considered unsuitable due to damage from a fire, storm, or other
insured disaster. It covers hotel bills, restaurant meals, and other living expenses incurred
while the home is being rebuilt.
, Coverage A - CORRECT ANSWER This coverage pays to repair or rebuild a home if it
is damaged or destroyed by fire, hurricane, hail, lightning, or other disasters listed in the
policy.
What does Coverage A not include? - CORRECT ANSWER It will not pay for damage
caused by a flood, earthquake, or routine wear and tear.
Coverage B - CORRECT ANSWER Personal property coverage helps to pay for your
personal items that have been damaged, destroyed or stolen due to a covered peril.
Coverage F - CORRECT ANSWER Medical payments coverage, part of your
homeowners insurance, can help pay for small injuries that happen to your guests on your
property, regardless of who is at fault.
This portion of your policy is designed to resolve smaller claims so they don't escalate into
lawsuits.
What are some structures that are covered by Coverage B? - CORRECT ANSWER
Detached garage.
Work shed.

claims arising from injuries or damage to other people or property.
Coverage C - CORRECT ANSWER Personal property coverage, which helps to pay for
your personal items that have been damaged, destroyed or stolen due to a covered peril.
