| Question | Answer |
|---|---|
| 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 |
