Fichas del conjunto (35)
- 1examples of thermal energy for heating and cookingopen fires, pioneer stoves, igloos, modern fireplaces, wood burning fire places, sod house soddies, solar heating
- 2the temperature of freezing point, melting point, boiling point and condensationfreezing is 0 degrees, melting is 0 degrees, boiling is 100 degrees and condensation is 100 degress
- 3Absolute zerois the coldest possible temperature- 273 degrees
- 4sensorwhich is affected by changes in a feature of the environment, such as temperature
- 5thermalcoupleit creates electricity when its heated
- 6Bimetallic Stripis made with two different mentals that are together
- 7thermometersThermometers are more reliable devices that measure temperature
- 8the three states of mattersolid liquid gas
- 9most particlesgas and least is solid
- 10what is the phenomenon when liquid evaportaes?- evaporative cooling
- 11another techiqune for seeing how hot or cold he temperature isobserving the colour
- 12if extreme high preasure can cause a ice to melt at the temperature ofmelt is below 0 degrees and boiling is below 100 degrees
- 13the recordings of thermommeterwhen a bimetallic strip is attached to a long arm lever
- 14solid liquid gas pariclesparticles are closley packed together is called solid, liquid particles slip past eachother and gas particles have alot of space between them.
- 15temperature and the particles of matterwhen heat is added to a substances the particles will move faster
- 16what is energyenergy is a measure of a substance the ablilty to do work and cause changes
- 17the four keys of particles of matterall matter is made up of extremely tiny particles, the tiny particles of matter are always moving, the particles have spaces between them, adding heat to matter makes the particles move around faster
- 18expandincreases there volume as the temperature increases
- 19contractdecreases the volume as the temperature decreases
- 20soild liquid gas shape and size and volumesolid keeps it shape and size the same cannot be conpressed liquid take the shape of the container almost incompressible gas no definite shape or size can be compressed
- 21radiation transfer energyenergy that can be transferred even though there are no particles to transfer the energy
- 22dull darkobjects absorbes radiant energy when they cool
- 23light shinyobjects or surfaces do not absorb radiant energy
- 24conductorsis the process of treansfering thermal energy by direct collision of the particles
- 25covectionthe warmer particles transfer there energy to the cooler particles as they in curclur pattern
- 26energy soucethis is where the energy comes from that can be transferred throughout the energy system
- 27direction of energy transferenergy is always transferred away from the concentrated
- 28transformationsenergy that can change its own form when it transfers
- 29waste heatalmost all of the energy is transferred directly to particle to particle
- 30control systemsa control device can start and stop the transfer of energy
- 31chemcial energycan be transformed into thermal energy when wood or coal is burned
- 32mechical forcesforce that push or pull on a object
- 33geothermal energyremaining of thermal energy inside the earth
- 34fossil fuels-fossils are a trace of a living thing, these fossils contain chemicals which are used to make heat
- 35-Melting(fusion) -Freezing(solidification) -evaporation -sublimation -condensation -Sub- solid to liquid
- liquid to solid
- liquid to gas
-gas to liquid
-solid to gas
