| Question | Answer |
| examples of thermal energy for heating and cooking | open fires, pioneer stoves, igloos, modern fireplaces, wood burning fire places, sod house soddies, solar heating |
| the temperature of freezing point, melting point, boiling point and condensation | freezing is 0 degrees, melting is 0 degrees, boiling is 100 degrees and condensation is 100 degress |
| Absolute zero | is the coldest possible temperature- 273 degrees |
| sensor | which is affected by changes in a feature of the environment, such as temperature |
| thermalcouple | it creates electricity when its heated |
| Bimetallic Strip | is made with two different mentals that are together |
| thermometers | Thermometers are more reliable devices that measure temperature |
| the three states of matter | solid liquid gas |
| most particles | gas and least is solid |
| what is the phenomenon when liquid evaportaes? | - evaporative cooling |
| another techiqune for seeing how hot or cold he temperature is | observing the colour |
| if extreme high preasure can cause a ice to melt at the temperature of | melt is below 0 degrees and boiling is below 100 degrees |
| the recordings of thermommeter | when a bimetallic strip is attached to a long arm lever |
| solid liquid gas paricles | particles are closley packed together is called solid, liquid particles slip past eachother and gas particles have alot of space between them. |
| temperature and the particles of matter | when heat is added to a substances the particles will move faster |
| what is energy | energy is a measure of a substance the ablilty to do work and cause changes |
| the four keys of particles of matter | all 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 |
| expand | increases there volume as the temperature increases |
| contract | decreases the volume as the temperature decreases |
| soild liquid gas shape and size and volume | solid 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 |
| radiation transfer energy | energy that can be transferred even though there are no particles to transfer the energy |
| dull dark | objects absorbes radiant energy when they cool |
| light shiny | objects or surfaces do not absorb radiant energy |
| conductors | is the process of treansfering thermal energy by direct collision of the particles |
| covection | the warmer particles transfer there energy to the cooler particles as they in curclur pattern |
| energy souce | this is where the energy comes from that can be transferred throughout the energy system |
| direction of energy transfer | energy is always transferred away from the concentrated |
| transformations | energy that can change its own form when it transfers |
| waste heat | almost all of the energy is transferred directly to particle to particle |
| control systems | a control device can start and stop the transfer of energy |
| chemcial energy | can be transformed into thermal energy when wood or coal is burned |
| mechical forces | force that push or pull on a object |
| geothermal energy | remaining of thermal energy inside the earth |
| fossil fuels | -fossils are a trace of a living thing, these fossils contain chemicals which are used to make heat |
| -Melting(fusion) -Freezing(solidification) -evaporation -sublimation -condensation -Sub | - solid to liquid - liquid to solid - liquid to gas -gas to liquid -solid to gas |
