Question

The temperature of liquid nitrogen is -196 °C. What is this temperature in Kelvins, and in degrees Fahrenheit?

Answer 1

First, let's see the formulas that we're going to use to convert from Celsius to Kelvin and Fahrenheit:

`\begin{gathered} K=\degree C+273, \\ F=1.8\cdot\degree C+32. \end{gathered}`

°C would be -196 °C. So we're going to have:

`\begin{gathered} K=-196+273=77K, \\ F=1.8\cdot(-196)+32=-320.8\text{ F.} \end{gathered}`

The temperature of liquid nitrogen of -196 °C in Kelvin is 77 K and in Fahrenheit is -320.8 F.
