SCIENCE TEST

Thermal Enegy

DESCRIPTIONANSWER
temperature at which no more energy can be removed from matter absolute zero
process that occurs when vaporization takes place only on the surface of a liquid evaporation
process that occurs when vaporization takes place inside a liquid as well as on the surface boiling
a material that conducts heat well….a material through which charges can easily flow conducto (wood, aluminum)
a material that DOESN'T conduct heat well a material through which charges can't easily flow (rubber,glass) insulator
a measure of the average energy of motion of the particles of a substance temperature
how does heat move a warmer object to a colder object
how does thermal energy effect the change of state of matter absorbs heat through sublimation, melting, evaporation/ releases heat through condensation and freezing
what is the movement of thermal energy in melting solid absorbing heat to become a liquid
what is the movement of thermal energy in condensation a gas releasing heat to become a liquid
how does a thermometer work temperature changes cause the level of the liquid inside a thermometer to rise and fall red alcohol that rises and fall due to convection or radiation
how do degrees compare to celsius and fahrenheit scale the degrees on the celsius scale are larger and the the degrees on the fahrenheit scale are smaller
whats the melting point for celsius 0 degrees
whats the boiling point for celsius 100
whats the room temperature for celsius 22
whats the melting point for Fahrenheit 32
whats the boiling point for Fahrenheit 212
whats the room temp for Fahrenheit 72
whats the melting point for kelvin 273
whats the boiling point for kelvin 373
whats the room temp for kelvin 0
convection is when what moves hot matter
radiation doesn't move through what atoms
atoms in the sun shoot off protons
the study of heat is called thermodynamics
all things are made of matter
matter is made of tiny parts
atoms are tiny parts
no one can do what see an atom (takes a very strong microscope)
heat is about what moving atoms
atoms move less in... in cold things
heat moves in three waves... convection conduction radiation
conduction is when heat energy moves
hot atoms do what to cold atoms pass heat to them
inside heat endothermic
outside heat exothermic
energy absorbed from the surroundings is an example of endothermic
energy given off to the surroundings is an example of exothermic
melting evaporization boiling endothermic
combustion condensation freezing exothermic
less energy more product endothermic
more energy less product exothermic
cooking popping popcorn vinegar and baking soda soda and mentor are all examples of endothermic
starting a car lightning lighting a match are all examples of exothermic
