Question

The liquid nitrogen temperature is 63 K. Convert to ºC.

Answer 1

`T_c=-210.15^(\circ)C`

Step-by-step explanation:

In this question we need to convert the temperature in kelvin to degree Celsius. The conversion from kelvin scale to Celsius scale is as follows :

`T_k=T_c+273.15`

Here,

`T_k=63\ K`

`T_k-273.15=T_c`

`63-273.15=T_c`

`T_c=-210.15^(\circ)C`

Here, negative sign shows that the heat is released. So, the temperature at 63 K is equivalent to 210.15 °C. Hence, this is the required solution.
