ILTS CONTENT TEST ELEMENTARY ED(305)-PART 3-6QUESTIONS WITH CORRECT ANSWERS
4 basic laws of thermodynamics - CORRECT ANSWER -zeroth law: states that 2
objects in thermodynamic equilibrium with a 3rd object are also in equilibrium
with each other
1st law: states that neither mass nor energy can be destroyed; only converted
from 1 form to another(conservation of energy)
2nd law: states that the entropy of an isolated system can only increase; heat is
not transferred from low temp system to a higher temp system one unless
additional work is done
3rd law: states that as a temperature approaches absolute 0, entropy approaches
a constant minimum; system can not be cooled to absolute 0.
compare and contrast heat and temperature - CORRECT ANSWER -heat: energy
transfer from 1 body or system to another due to thermal contact
temperature: measurement of an object's stored heat energy
mass - CORRECT ANSWER -measures how much of a substance is in an object
weight - CORRECT ANSWER -measures the gravitational pull of the earth on an object
density - CORRECT ANSWER -a measure of the amount of mass in a given volume
ILTS Content Test Elementary Ed(305)-Part 3-6 Questions with correct answers
,D=m/V
volume - CORRECT ANSWER -measures the amount of space taken up
specific gravity - CORRECT ANSWER -measures the ratio of a substance's density to
the density of water
thermal contact - CORRECT ANSWER -energy transferred to a body by a means other
than work
heat - CORRECT ANSWER -The energy transferred between objects that are at
different temperatures
Models for the flow of electric charge - CORRECT ANSWER -used to explain the flow
of electric current, potential, circuits include water, gravity and roller coasters
magnetic field - CORRECT ANSWER -motion of subatomic structures(nuclei and
electrons) produce magnetic field; formed not only by magnetic material but also
by electric current flowing through a wire
magnetic moment - CORRECT ANSWER -The strength of a magnetic field
electric charges as they relate to atomic structure - CORRECT ANSWER -electric
force: attractive force between the electrons and the nucleus
ILTS Content Test Elementary Ed(305)-Part 3-6 Questions with correct answers
,*electrical field: positive or negative charge creates a field of sorts in the empty
space around it
*electric charge: measured with unit Coulomb(C) is the amount of charge moved
in 1 second by a steady current of one ampere(1C=1Ax1s
electric current - CORRECT ANSWER -The continuous flow of electric charges through
a material
rate of flow of electric charge - CORRECT ANSWER -expressed using the ampere(amp
or A) and can be measured using an ammeter
simple circuit - CORRECT ANSWER -a circuit that has only one pathway for electricity
to flow through.
example: flow from 1 terminal of a car battery to another
magnet - CORRECT ANSWER -a piece of metal, such as iron, steel or magnetite that
can affect another substance within its field of force that has like characteristics
2 poles: north and south
magnetism - CORRECT ANSWER -The force of attraction or repulsion of magnetic
materials
magnetic domain - CORRECT ANSWER -occurs when the magnetic fields of atoms are
grouped and aligned. These groups form what can be thought of as miniature
ILTS Content Test Elementary Ed(305)-Part 3-6 Questions with correct answers
, magnets within a material. This is what happens when an object like an iron nail is
temporarily magnetized. Prior to magnetization, the organization of atoms and
their various polarities are somewhat random with respect to where the north
and south poles are pointing. After magnetization, a significant percentage of the
poles are lined up in one direction, which is what causes the magnetic force
exerted by the material.
motion - CORRECT ANSWER -change in location of an object and is the result of an
unbalanced net force acting on the object
displacement - CORRECT ANSWER -Distance and direction of an object's change in
position from the starting point.
gravitational force - CORRECT ANSWER -a universal force that causes every object to
exert a force on every other object
F=Gm1m2/r^2
m1 and m2 are the masses of two objects
r is distance between them
G is the gravitational constant G=6.672x10^-11 N-m^2/kg^2
force of gravity is calculated as F=mg
g=9.81m/s^2
