Question

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​

Answer 1

AnSwer :-

☄ the triple point of neon :- 24.57K

☄ the triple point of carbon dioxide :- 216.55K

Kelvin and Celsius scales are related as

$\boxed {\bf T_C = T_K - 273.15}$

Celsius and Fahrenheit scales are related as

$\boxed {\bf T_F = (9/5) T_C + 32}$

For neon :-

T$\sf _K$ = 24.57 K ⠀⠀⠀⠀⠀ [given]

we know,

➠ T$\sf _C$ = T$\sf _K$ – 273.15

➠ T$\sf _C$ = 24.57 – 273.15

➠ T$\sf _C$ = –248.58°C

then,

➠ T$\sf _F$ = (9/5)T$\sf _C$ + 32

➠ T$\sf _F$ = (9/5)T$\sf _C$ + 32

➠ T$\sf _F$ = (9/5) × (-248.58) +32

➠ T$\sf _F$ = - 415.440 F

thus, temperatures on the Celsius scale is -248.58°C and Fahrenheit scale is - 415.44F

Similarly,

For carbon dioxide :-

T$_K$= 216.55 K ⠀⠀⠀⠀⠀[given]

➠ T$\sf _C$ = T$\sf _K$ – 273.15

➠ T$\sf _C$ = 216.55 – 273.15

➠ T$\sf _C$ = –56.60°C

then,

➠ T$\sf _F$ = (9/5)T$\sf _C$ + 32

➠ T$\sf _F$ = (9/5)T$_C$ + 32

➠ T$\sf _F$ = (9/5) × (-56.60) +32

➠ T$\sf _F$ = -69.880 F

thus, temperatures on the Celsius scale is -56.69°C and Fahrenheit scale is -69.880F

|| Note :- The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. ||

Answer 2

Explanation:

concept :-

K = C + 273.15

and C/5 = ( F - 32)/9

Where, K is Kelvin , C is Calcius and F is Fahrenheit.

For 24.57 K

In calcius ,

C = 24.57 - 273.15

C = -248.58° C

In Fahrenheit ,

-248.58/5 = ( F - 32)/9

F = -248.58 × 9/5 + 32

= -414.44°F

For 216.55 K,

in Celsius ,

C = 216.55 - 273.15

= -56.6°C

In Fahrenheit,

-56.6/5 = ( F - 32)/9

F = -56.6×9/5 + 32

= -69.88°F
