Total: 22
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:  
Here, Triple point of neon, T1=24.57K
Triple point of CO2,T2=216.55K
Relation between kelvin scale and celsius scales
TC=TK273.15
where TC= Temperature on celsius scale
TK= Temperature on kelvin scale
For neon TC=24.57273.15=248.58°C
For CO2,TC=216.55273.15
=56.60°C
Relation between kelvin and Fahrenheit scales is
