\nThe Kelvin temperature scale is an absolute scale where 0 K is absolute zero. The Celsius scale is a relative scale where 0\u00b0C is the freezing point of water. The size of one degree Celsius is equal to the size of one kelvin. The relationship between Kelvin temperature (T) and Celsius temperature (t_c) is given by the formula T = t_c + 273.15. This means that a temperature in Celsius can be converted to Kelvin by adding 273.15.
\n<\/section>\n
\n– The Kelvin scale starts at absolute zero (0 K), where particle motion theoretically stops.
\n– The Celsius scale is based on the phase change points of water at standard pressure (0\u00b0C for freezing, 100\u00b0C for boiling).
\n– The temperature 0\u00b0C corresponds to 273.15 K.
\n– The formula T = t_c + 273.15 correctly shifts the zero point of the Celsius scale to match the absolute zero of the Kelvin scale while maintaining the same interval size.
\n<\/section>\n
\nFor most practical purposes and in many physics problems, the value 273.15 is often approximated as 273. The freezing point of water is exactly 273.15 K and the boiling point is 373.15 K. The Kelvin scale is the standard unit of thermodynamic temperature in the International System of Units (SI).
