3. What scales are used to measure TEMPERATURE?
4. TEMPERATURE SCALESFahrenheit scaleInvented in 1724Named after German physicist, Daniel Gariel FahrenheitDefined in terms of water:freezes at 32°Fboils at 212°F (at 101.32 kPa)Still used in USA and its territorieshttp://intermath.coe.uga.edu/dictnary/images/miscell/frnthrmtr.gif
5. TEMPERATURE SCALESCelsisus scaleInvented in 1742Named after Swedish astronomer, Anders CelsiusDefined in terms of water:freezes at 0°Cboils at 100°C (at 101.32 kPa)Used worldwide except when Fahrenheit scale is predominanthttp://intermath.coe.uga.edu/dictnary/images/miscell/frnthrmtr.gif
6. Converting between °F→°C & °C→°F°F to °CSubtract 32Multiply by 5Divide by 9°C to °FMultiply by 9Divide by 5Add 3298.6 °F 98.6 – 32 = 56.666.6* 5 = 333333 / 9 = 37So, 98.6 °F = 37 °C100 °C 100 * 9 = 900900 / 5 = 180180 + 32 = 212So, 100 °C = 212 °F http://nauticajonkepa.files.wordpress.com
7. For what types of measurements are the Fahrenheit and Celsisus scales usually used?Weather forecastsBaking & cookingClothes washingComputer diagnosticsHealth – fever or no fever?Air temperatureOven or Food temperatureWater temperatureCPU temperatureBody temperature
8. What is the “layman‘s” definition of temperature?Temperature is a measure of how HOT or COLD something is.
9. What is the “scientist‘s” definition of temperature?Temperature refers to the kinetic energy of a substance‘s moving particles.↓ temperature = slower movement ↑ temperature = faster movementhttp://imshopping.rediff.com
10. THE SPEAKER SAID “zero degrees kelvin (0°K)” – THIS IS INCORRECTINSTEAD WE SAY “zero kelvin (0 K)”
11. Temperature scalesKelvin scaleInvented in 1848Named after British engineer and physicist, William Thomson (1st Baron Kelvin)Defined in terms of absolute zero which is the same for all substances 0 K = - 273.15°CKelvin is an SI base unithttp://www.differencebetween.info
