Comparing temperatures in centigradeS
Is 20 C twice as hot as 10 C? No – because the centigrade scale does not start at 0.
For e.g.- if we used a meter scale that started at 1.0 meters, what can you say about comparing 1.1 to 1.2? Can you say that 1.2 is TWICE as high as 1.1? Obviously not -because your zero is skewed.
The only way we can truly compare temperatures is if we use the kelvin scale, since the absolute zero of temperature is zero on the Kelvin Scale.
