- Fahrenheit (°F): by a German physicist Daniel Gabriel Fahrenheit in 18th Century (commonly used in English-speaking countries until the 1970s)
- Kelvin (K): by a British physicist William Thomson, 1st Baron Kelvin in 1848; The base unit of thermodynamic temperature measurement; Adopted as the International Standard for scientific temperature measurement. ]]> 2017-02-05 07:31:32 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151641083 yusu111079 https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151649002 * Celsius to Fahrenheit: Multiply by 9/5, then add 32

Traditional/Analogue Thermometer: Normally uses mercury or alcohol to measure temperature.
2. Infrared Thermometers: These thermometers use infrared rays to measure the body’s temperature.
3. Digital Thermometer: Uses electronic heat sensors to detect body temperature.]]> 2017-02-05 11:35:47 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151651808 jaso110042 https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151651901 -It is the thermometer which there be liquid in the thermometer itself.
-The liquid usually used is mercury.
-This liquid has been around for 300 years.
-it is oftenly use in the lab]]> 2017-02-05 11:37:52 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151651901 jaso110042 https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151652712 -Calibration of a thermometer is really important .
-Because if we do not calibrate the thermometer 
it could show the wrong temperature .]]> 2017-02-05 11:54:30 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151652712 limh110189 https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151652925 2017-02-05 11:58:37 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151652925 limh110189 https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151653547 2017-02-05 12:11:49 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151653547 limh110189 https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151653598 2017-02-05 12:12:52 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151653598 jaso110042 https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151653697 2017-02-05 12:15:04 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151653697 limh110189 https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151653739 A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created. The voltage can then be interpreted using thermocouple reference tables to calculate the temperature. ]]> 2017-02-05 12:15:51 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151653739 jaso110042 https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151653780 2017-02-05 12:16:42 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/151653780 https://padlet.com/yusu111079/f3oi3i6pqvca/wish/153330635 How to tell if hot: If it has more heat energy]]> 2017-02-13 02:23:03 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/153330635 https://padlet.com/yusu111079/f3oi3i6pqvca/wish/153331289 -273.15]]> 2017-02-13 02:30:18 UTC https://padlet.com/yusu111079/f3oi3i6pqvca/wish/153331289
