Question

The triple point of carbon dioxide is `216.55` K the corresponding temperature on the celsius and Fahrenheit scale respectively are
A. `56.45^(@)C, -69.61^(@)F`
B. `-56.45^(@)C, 69.61^(@)F`
C. `54.45^(@)C,69.61^(@)F`
D. `-5445^(@),-6961^(@)F`

Answer 1

Correct Answer - D
As `T_(C) = (T - 273)^(@)C`
`= 216.55 - 273 = -54.45^(@)C`
Also, `T_(F) = (9)/(5) T_(C) + 32 = 9/ 5 xx (-56.45) + 32`
`= - 101.61 + 32 = -69.61 .^(@)F`
