What is the value of 0°C in Kelvin?

To convert Celsius to Kelvin, you use the formula:

[ K = °C + 273.15 ]

In this case, when you substitute 0°C into the formula, you get:

[ K = 0 + 273.15 = 273.15 ]

This means that 0 degrees Celsius is equivalent to 273.15 Kelvin. The Kelvin scale starts at absolute zero (0 K), which is the theoretical point where all molecular motion stops. Therefore, temperatures in Kelvin are always positive.

This understanding of temperature conversion is critical in scientific contexts, especially in chemistry, where Kelvin is the standard unit for temperature in gas law equations and other calculations.
