|---|---|---|---|---|---|
| temperature | Is a measure of the average kinetic energy of the individual particles in an object
🗑
|
||||
| Fahrenheit scale | The temperature scale on which 32 and 212 are the temperature at which water freezes and boils
🗑
|
||||
| Celsius scale | The temperature scale on which zero and 100 are the temperature at which water freezes and boils
🗑
|
||||
| Kelvin scale | The temperature scale on which zero is the temperature at which no more energy can be removed from matter
🗑
|
||||
| absolute zero | The temperature at which no more energy can be removed from matter
🗑
|
||||
| conduction | The transfer of heat between particles within a substance
🗑
|
||||
| heat is transferred by | conduction,convection,radiation
🗑
|
||||
| convection | The moverment that transfer heat within the water
🗑
|
||||
| radiation | Is the transfer of energy by electromagnetic waves
🗑
|
||||
| conductor | A material that conducts tranfers heat between its particles
🗑
|
||||
| Insulator | A material that dose not conduct heat well ex:wood,wool,straw,paper,and cork also gases, such as air are also good insulator
🗑
|
||||
| specific heat | The amount of energy requried to raise the temperature of 1 kilogram of a substance by 1 kelvin
🗑
|
||||
| specific heat of common substance is Aluminum | 903
🗑
|
||||
| specific heat of common substance is Brass | 376
🗑
|
||||
| specific heat of common substance is Copper | 385
🗑
|
||||
| specific heat of common substance is Glass | 664
🗑
|
||||
| specific heat of common substance is Ice | 2,060
🗑
|
||||
| specific heat of common substance is Iron | 450
🗑
|
||||
| specific heat of common substance is Sand | 670
🗑
|
||||
| specific heat of common substance is Silver | 235
🗑
|
||||
| specific heat of common substance is Water | 4,180
🗑
|
||||
| heat | Is the movement of thermal energy from a substance at a higher temperature to another at a lower temperature
🗑
|
||||
| convection current | A current caused by the rising of heated fluid and sinking of cooled fluid
🗑
|
||||
| the formula for change in energy | mass x specific heat x change in temperature
🗑
|
||||
| solids | the particles that make up a solid are packed close and cannot move out of position but can vibrate and they have a fixed shape and fixed volume
🗑
|
||||
| liquids | particles are close but not as tight as in a solid and don't have a definite shape but they do have a fixed volume
🗑
|
||||
| gasses | particles are moving so fast, they are not close and they expand to fit all available space. No fixed shape or volume
🗑
|
||||
| solid to liquid | this change is called melting. More thermal energy=less rigidness in particles and more movement and the temperature at which this change occurs is its melting pot
🗑
|
||||
| liquid to solid | this change of state is called freezing. A substance losses thermal energy.
🗑
|
||||
| liquid to gas | this change in state is called vaporization. This liquid adsorb thermal energy and the particles escape the liquid and are now gas particles. Boiling- when vaporization takes place and leads to evaporation
🗑
|
||||
| gas to liquid | this change in state is called condensation. This is when a gas loses thermal energy
🗑
|
||||
| thermal energy | the total energy of the particles in an object.
🗑
|
||||
| thermal expansion | is the expanding of matter when its heated
🗑
|
||||
| state | solid, liquid and gas
🗑
|
||||
| change of state | the physically change from one state of matter to another
🗑
|
||||
| meting | the change of state from a solid to a liquid
🗑
|
||||
| melting point | the temperature at which a substances melts
🗑
|
||||
| freezing point | the temperature at which a substance freezes
🗑
|
||||
| vaporization | the process by which matter changes from the liquid to the gas state
🗑
|
||||
| evaporation | vaporization that occurs at the surface of a liquid
🗑
|
||||
| boiling | vaporization that occurs on and below the surface of a liquid
🗑
|
||||
| boiling point | the temperature that a liquid substances boils
🗑
|
||||
| condensation | a change from the gas state to the liquid state
🗑
|
||||
| thermostat | a device that regulates tempertaure
🗑
|
||||
| bimetallic strip | a strip made of different metals that expand at different rates
🗑
