How is temperature calculated when converting Celsius to Kelvin?

• A. K = C + 100
• B. K = C + 250
• C. K = C + 273.15
• D. K = C + 0.15

Answer: (C)

To convert temperature from degrees Celsius to Kelvin, the correct formula is to add 273.15 to the Celsius temperature. This is because the Kelvin scale is an absolute temperature scale that starts at absolute zero, which is 0 K. In the Celsius scale, absolute zero is equivalent to -273.15 °C. Therefore, to find the Kelvin value, you need to offset the Celsius temperature by this amount. Using the formula K = C + 273.15 ensures that you are properly adjusting the temperature measurement to align with the Kelvin scale, which is commonly used in scientific contexts for its absolute nature. This method allows for calculations involving temperature that require an absolute reference point, essential for thermodynamic equations and other scientific applications.
