Changes

'''Degrees Celsius''' are the a scientific [[unit]]s of [[temperature]].

: '''Degrees Celsius''' is shortened to '''°C''' with the degree symbol ° followed by capital an upper case C.: A '''degree Celsius''' is 100th of the [[temperature]] change between the [[ice]] [[melting]] and [[water]] [[boiling]]. ==Key Stage 4=====Meaning==='''Degrees Celsius''' are a scientific [[unit]] of [[temperature]]. ===About Degrees Celsius===: '''Degrees Celsius''' is shortened to '''°C''' with the degree symbol ° followed by an upper case C.: '''Degrees Celsius''' are 273° away from the [[SI Unit|SI unit]] for [[temperature]]; the [[Kelvin]];:*0'''°C''' = 273 [[Kelvin]]:*-273'''°C''' = 0 [[Kelvin]] ([[Absolute Zero]] the coldest [[temperature]] possible in the [[Universe]]).: A change of 1'''°C''' is the same as change of 1 [[Kelvin]].: A '''degree Celsius''' is 100th of the [[temperature]] change between the [[Melting Point|melting point]] and [[Boiling Point]]|boiling point]] of [[water]] at normal [[Atmospheric Pressure|atmospheric pressure]]. ====OCR====:[https://www.amazon.co.uk/gp/product/0198359837/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=0198359837&linkCode=as2&tag=nrjc-21&linkId=3c4229e8b023b2b60768e7ea2307cc6f ''Degrees Celsius, pages 26, Gateway GCSE Physics, Oxford, OCR ''] ==Key Stage 5=====Meaning==='''Degrees Celsius''' are a [[unit]] of temperature in the [[Degrees Celsius|Celsius scale]] where 0°C is the [[temperature]] at which [[water]] [[Freezing|freezes]] and 100°C is the [[temperature]] at which [[water]] [[boil]]s at [[Standard Atmospheric Pressure|standard atmospheric pressure]]. ===About the Celsius Scale===*Defined in terms of the [[Triple Point|triple point]] of [[water]], where the [[temperature]] is exactly 0.01'''°C'''.*Used worldwide for most [[temperature]] [[measure]]ments except in scientific research where the [[Absolute Temperature|Kelvin scale]] is preferred.*Named after the Swedish astronomer Anders Celsius.*Commonly used in everyday [[temperature]] [[measure]]ments and weather reporting.*The '''Celsius''' scale is part of the [[Metric System|metric system]].*The interval between the [[freezing]] and [[boiling]] points of [[water]] is divided into 100 '''degrees'''.*The '''Celsius''' scale is also used in various scientific and engineering contexts. ===Examples===*Weather forecasts report temperatures in degrees '''Celsius'''.*Laboratory measurements often use the '''Celsius''' scale for [[temperature]] readings.
