Thermal Properties of Matter

Question : 1

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=TK–273.15
where TC= Temperature on celsius scale
TK= Temperature on kelvin scale
For neon TC=24.57–273.15=–248.58°C
For CO2,TC=216.55–273.15
=–56.60°C
Relation between kelvin and Fahrenheit scales is
F=

C+32
For neon TF=

×−248.58+32
=−415.44° F
For CO2TF=

×−56.60°+32
=−69.88° F
