Thermal Properties of Matter – Solutions

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:

Relation between the Celsius and Fahrenheit scale is:

T_F = 9/5 T_C+32      ———–(1)

Relation between Kelvin and Fahrenheit scale is:

T_C = T_K -273.15    —-(2)

For carbon dioxide:

T_{K = 216.55 K}

T_C = 216.55 – 273.15 = -56.60⁰C
