Which of the following represents the relationship between Celsius and Kelvin?

The correct relationship between Celsius and Kelvin is given by the formula K = C + 273.15. This equation indicates that to convert a temperature from Celsius to Kelvin, you need to add 273.15 to the Celsius temperature.

The Kelvin scale is an absolute temperature scale that starts at absolute zero, which is the theoretical point where molecular motion ceases. The freezing point of water is 0 degrees Celsius, which corresponds to 273.15 Kelvin. Therefore, by adding 273.15 to a Celsius temperature, you effectively shift it to the Kelvin scale.

For example, if the temperature is 25 degrees Celsius, to find the equivalent in Kelvin, you would calculate 25 + 273.15, resulting in 298.15 K. This shows how the two temperature scales are related and why the given formula is valid.
