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

Explanation

(1) Triple point for Neom `T=24.57` K
`:.T_(C)=T(K)-273.15`
`=24.57-273.15`
`=-248.58^(@)C`
Now, `T_(F)=9/5T_(C)+32`
`=9/5(-248.58)+32`
`=-447.44+32`
`=-415.44^(@)F`
(2) Triple point for `CO_(2),T=216.55K`
`T_(C)=T(K)-273.15`
`=216.55-273.15`
`=-56.6^(@)C`
`:.T_(F)=9/5T_(C)+32`
`=9/5(-56.6)+32`
`=-101.88+32`
`=-69.88^(@)F`
