How are the Celsius and Kelvin scales built?

The Celsius scale is based on two fixed temperatures. The first value is the melting temperature of pure ice at normal atmospheric pressure. This temperature is taken as 0 ° C. The second value is the boiling point of pure water. This temperature is taken as 100 ° C. The distance between these marks is divided into 100 equal parts. Print 1 ° С per unit temperature Kelvin scale is based on the laws of thermodynamics. The temperature at which the body cannot transfer heat to any other body was taken as zero Kelvin. For the unit of temperature on the Kelvin scale, the temperature is 1 Kelvin, which is equal to one degree Celsius.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
