Question

F= 5 9 ​ (K−273)+32space, F, equals, start fraction, 9, divided by, 5, end fraction, left parenthesis, K, minus, 273, right parenthesis, plus, 32 In order to convert a temperature in Kelvin, KKK, into a temperature in degrees Fahrenheit, FFF, the equation above can be used. Which of the following equations correctly expresses the temperature in Kelvin in terms of the temperature in degrees Fahrenheit?

Answer 1

use euclid division algorithm to find hcf of 135 and 225

Answer 2

Answer:

$K=\frac{5}{9}(F-32)+273$

Step-by-step explanation:

The given formula to convert a temperature in Kelvin, K, into a temperature in degrees Fahrenheit, F is

$F=\frac{9}{5}(K-273)+32$

We need to find the formula to convert a temperature in degrees Fahrenheit, F, into a temperature in Kelvin, K.

Subtract 32 from both sides.

$F-32=\frac{9}{5}(K-273)+32-32$

$F-32=\frac{9}{5}(K-273)$

Multiply both sides by 5/9.

$\frac{5}{9}\times (F-32)=\frac{5}{9}\times \frac{9}{5}(K-273)$

$\frac{5}{9}(F-32)=K-273$

Add 273 on both sides.

$\frac{5}{9}(F-32)+273=K-273+273$

$\frac{5}{9}(F-32)+273=K$

Therefore the required equation is $K=\frac{5}{9}(F-32)+273$.
