Question

If celsius temperature scale shows temperature of air 30^(@)C. Find the temperature of air in fahrenheit & kelvin.

Answer 1

$\Large{\underline{\underline{\bf{Solution :}}}}$

We know that,

$\large{\implies{\boxed{\boxed{\sf{\frac{C}{5} = \frac{K - 273}{5} = \frac{F - 32}{9}}}}}}$

Where,

C = Celsius

F = Fahrenheit

K = Kelvin

$\rule{150}{2}$

C = 30°

Now, A.T.Q

$\sf{→\frac{\cancel{30}}{\cancel{5}} = \frac{F - 32}{9}} \\ \\ \sf{→6 \times 9 = F - 32} \\ \\ \sf{→54 + 32 = F} \\ \\ \sf{→F = 86}$

Temperature in Fahrenheit scale = 86°

$\rule{200}{2}$

$\sf{→\frac{\cancel{30}}{\cancel{5}} = \frac{273 - K}{5}} \\ \\ \sf{→273 - K = 5 \times 6} \\ \\ \sf{→273 - K = 30} \\ \\ \sf{-K = 30 - 273} \\ \\ \sf{K = 243^{\circ}}$

Answer 2

Explanation:

We're given a temperature in degrees Fahrenheit, and asked to convert this temperature to Kelvin.

One way to convert a temperature value from degrees Fahrenheit to Kelvin is to first convert it to degrees Celsius, and then directly calculate that to Kelvin.

The formula for converting a temperature from

o

F

to

o

C

is given by

o

C

=

5

9

(

o

F

−

32

)

In simple words, subtract

32

from the Fahrenheit temperature, multiply that number by

5

, and then divide that by

9

to get the Celsius temperature.

Plugging in our known temperature value, the temperature in

o

C

is
