the boiling point(100), the freezing point(0), and room temperature(20)
No, in Celsius temperature scale, lower temperatures are colder and higher temperatures are hotter.
Yes. Beginning in 1970, Australia adopted the use of the Celsius (centigrade) scale for temperatures.
It can be used with any temperature. However the Kelvin scale (centigrade based on absolute zero) is often used for very cold temperatures, or for very hot temperatures, where it is practically the same as Celsius.
The Celsius scale can give negative temperatures when measuring temperatures below zero degrees Celsius. This is because zero degrees Celsius is the freezing point of water, and temperatures below freezing are represented as negative values on the Celsius scale.
Both and neither. Celsius is a temperature scale and as such, covers a wide range of temperatures.
No, Celsius is a temperature scale which can go down to -273.15. The hottest temperature attained by scientists is approx 4 trillion degrees and the theoretical maximum is 1.4*10^32 [140 nonillion] degrees. On balance, then, the range of negative temperatures on the Celsius scale is somewhat smaller than the positive temperatures.
That's wrong. That's not how you convert temperatures between Celsius and Fahrenheit.
The pure water freezing point (zero degree) and its boiling point (100 degrees) at atmospheric pressure.
The Kelvin scale is based at absolute zero. The Kelvin scale was defined when the scientist William Thomson (1st Baron Kelvin) calculated the absolute minimum thermal energy an object can have. He decided to shift the Celsius scale so that 0 would be equivalent to having zero thermal energy (aka absolute zero).
A thermometer that measures temperatures on the Kelvin scale would have its zero point at absolute zero (-273.15°C), while one that measures temperatures on the Celsius scale has its zero point at the freezing point of water (0°C). Additionally, Kelvin is an absolute scale with no negative values, while Celsius has both positive and negative values.
Celsius is a temperature scale where 0 degrees represents the freezing point of water and 100 degrees represents the boiling point of water. While it is often used to measure cold temperatures, Celsius itself does not specifically mean "cold."
Both. It's a scale that covers a wide range of temperatures.
