SCIENCE TEST
Thermal Enegy
| DESCRIPTION | ANSWER |
|---|---|
| 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 |
