Hint: To know about the relation between \[{}^{o}C\]and Kelvin (K) we should know about the temperature. \[{}^{o}C\]and Kelvin (K) both are units of temperature.

Complete step by step answer:
* Temperature: “It is a measure of heat inside the matter or it is a measure of hotness of a substance”.
* Temperature can be measured by using degree Celsius\[{}^{o}C\]and Kelvin (K).
* Kelvin (K) is the IS unit to measure Temperature.
* But temperature is also measured in Celsius (\[C\]) and Fahrenheit (\[F\]).
* Kelvin is most preferable because it won’t be negative in normal use.
* The units of temperature are interchangeable.
* The relationship between Kelvin and Celsius is as follows
Kelvin = degree Celsius + 273

Or, K= \[{}^{o}C\]+ 273

* Zero on the Celsius scale (\[{}^{o}C\]) is now defined as the equivalent to 273.15 K, with a temperature difference of 1 deg \[C\] equivalent to a difference of 1K, meaning the unit size in each scale is the same.
* This means that 100 \[{}^{o}C\], previously defined as the boiling point of water, is now defined as the equivalent to 373.15 K.
* Boiling point of water is 100 degree Celsius or 373 Kelvin.
* Freezing point of the water is zero degree Celsius or 273 Kelvin.

Note: Don’t confuse between Celsius and Fahrenheit. “The Fahrenheit scale is a temperature scale proposed in 1724 by physicist Daniel Gabriel Fahrenheit. It uses the degree Fahrenheit (\[^{0}F\]) as the unit.
The relationship between Celsius and Fahrenheit is as follows
\[F=\dfrac{9}{5}C+32\]
