Question 1. 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. Solution :Kelvin and Celsiusscales are related as:TC = TK – 273.15 … (i)Celsius and Fahrenheit scales are related as:TF = (9/5)TC + 32   ….(ii)For neon:TK = 24.57 K∴ TC = 24.57 – 273.15 = –248.58°CTF = (9/5)TC + 32= …
