What is the value of 100 c on the kelvin scale

It should be 373.15k.

Zero on the Celsius scale (0℃) is now defined as the equivalent to 273.15K, 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℃, previously defined as the boiling point of water, is now defined as the equivalent to 373.15K.

Organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
