Ch 5 Lesson 1 Heat
| Question | Answer |
|---|---|
| temperature | is a measure of how hot or cold something is compared to a reference point |
| Celsius Scale | you can use an equation to convert between scales, but its simpler to estimate |
| absolute zero | is the lowest temperature possible |
| heat | is the transfer of thermal energy from a warmer object to a cooler object |
| fahrenheit scale | to measure temperature used by the United States |
| kelvin scale | celsius and fahrenheit scales divided into degrees |
| Convection | the type of heat transfer that occurs only in fluids |
| convection current | convection rents in air cause wind and weather changes |
| radiation | is the transfer of energy by electromagnetic waves |
| conduction | transfers heat from one particle of matter to another within an object or between two objects |
| conductor | a material that conducts heat well |
| insulator | materials that do not conduct heat well |
| specific heat | the amount of energy required ti raise the temperature of 1 kilogram of a material by 1 kelvin |
| thermal expansion | the expanding of matter when it is heated |
