PLEASE READ

This is basically a knock-off version of lunifer's test, but i did it all myself... so yeah... anyways, hope this test helps! <3

Types Of Heat Energy

Question Answer
MechanicalFriction, Percussion, Compression, Distortion
ChemicalBurning, Other (new substances are always formed with chemical sources of heat)
ElectricalElectrical doesn't have any sub-types... lol
NuclearFusion, Fission
memorize

Examples of Types of heat energy

Question Answer
Example of FrictionRubbing your hands against each-other and feeling warmth after.
Example of PercussionA nail becoming warm after it is being pounded by a hammer
Example of CompressionThe air inside a bicycle becoming warm when more air is being pumped into it.
Example of Distortionbending a coat-hanger or paper-clip repeatedly
Example of Burningnew substances are formed when change of energy occurs (not change of state of matter)
Example of Other chemical reactionsThe atoms in plaster of paris react with water, creating heat , again, like burning, new substances are being formed
Example of ElectricalAn oven ring heating up when being turned on
Example of NuclearFusion in the sun.
memorize

Definitions of Types of heat energy

Question Answer
FrictionHeat is produced when surfaces are rubbed together.
PercussionSubstances heat up when being hit or pounded.
CompressionWhen objects are compressed, they become hotter
DistortionHeat is generated when substances (mostly metals) are bent (usually repeatedly)
BurningHeat energy is released when the bonds between atoms (particles) are broken using high temperatures
Other chemical reactionsHeat energy is released when certain substances are mixed with others
Electricalas electricity moves through material that resists the flow of electrons (part of an atom) the particles in the substance become agitated and move more rapidly, generating heat
memorize
Fusion: when atoms are forced to join together
Question Answer
Fissionwhen atoms are forced apart
memorize

Define photons.they carry the radiation
Higher frequencies equal ______________higher energy
infrared radiation is ______HEAT
infrared camera colorsbright colors are warm/hot and dark colors are cool/cool
memorize

THE AMAZING SUN

Question Answer
What 3 common household electronics can be effected by solar flares?radio, television and cellphones
Does nuclear fusion of fission occur in the sun.fusion
What gas is formed when tritium and deuterium are collide and nuclear fusion occurs?Helium
Which two gasses fuel the sun?Hydrogen and Helium
memorize

Common Temperatures

Question Answer
HUMAN37
PIZZA OVEN160
FRIDGE7
ROOM TEMPERATURE20
memorize

Absolute 0

Question Answer
What temperature does absolute 0 occur in celsius?-273
What temperature does absolute 0 occur in kelvin?0
Are particles still moving at absolute zero?yes, but very, very slowly.
Has absolute zero ever been obtained?No.
memorize

How does heat affect the volume of matter?

Question Answer
Read the title.heat increases the movement of the particles in a substance and the distance they vibrate, so the volume increases.
memorize

Conversions

Question Answer
Celsius to Kelvin+273
Kelvin to Celsius-273
Celsius to Fahrenheit(C) x 1.8 +32
Fahrenheit to Celsius((F) - 32) /1.8
Kelvin to and from FahrenheitConvert to Celsius first.
memorize

Definitions

Question Answer
Heatthermal energy that can be transferred from one substance to another
Temperaturethe measure of the average kinetic energy of the molecules in the substances
Potential energyEnergy that is stored
Kinetic energyEnergy that is "moving"
ConductorsSubstances that transfer heat easily/quickly.
InsulatorsSubstances that transfer heat poorly.
memorize

Misc.

Question Answer
Who invented the first air thermometer?Galileo (galileo) Gallileo (gallileo) Gallileo figaro MANIFICO O O O O
There are many sources of electricity, name 4.1) Nuclear 2)Solar 3)Wind 4)Water
What percent of energy we get from food is used for heat?60%
memorize
