Question

Which equation shows the relationship between the Kelvin and Celsius temperature scales?

Answer 1

K = C + 273.15

and

C = K - 273.15

Answer 2

T(C) = T(K) + 273.15

T(K) = T(C) - 273.15

Step-by-step explanation:

Kelvin (K) is the scale used to measure the absolute temperature, and it is the SI unit for the temperature.

Another scale used is the Celsius degree (C), which is defined by using the freezing point and boiling point of water. In fact:

- The zero (0 C) in the Celsius scale is defined as the temperature at which the water freezes, and

- 100 C in the Celsius scale is defined as the temperature at which the water boils

The Celsius scale involves the possibility of having negative temperatures; instead, the zero in the Kelvin scale (0 K) is defined as the lowest possible temperature in the Universe. The conversion factors between the two scales are the following:

T(C) = T(K) - 273.15

T(K) = T(C) + 273.15
