Question

The triple points of neon and carbon dioxide are 24.57 K and 216.55 K respectively. Express these temperatures on the Celsius and Fahrenheit scales.

Answer 1

Kelvin and Celsius scales are related as:

T_C = T_K – 273.15 … (i)

Celsius and Fahrenheit scales are related as:

… (ii)

For neon:

T_K = 24.57 K

∴T_C = 24.57 – 273.15 = –248.58°C

For carbon dioxide:

T_K = 216.55 K

∴T_C= 216.55 – 273.15 = –56.60°C
