Question

Please help thank you.

Answer 1

a)

  F  = $\frac{5}{9}$(K - 273.15) + 32

- 32                          - 32

F - 32 = $\frac{5}{9}$(K - 273.15)

$\frac{9}{5}$(F - 32) = $\frac{9}{5}$[$\frac{5}{9}$(K - 273.15)]

$\frac{9}{5}$(F - 32) = K - 273.15

$\frac{9}{5}F$ - $\frac{9(-32)}{5}$ = K - 273.15

$\frac{9}{5}F$ - 57.6 = K - 273.15

    + 273.15       + 273.15  

$\frac{9}{5}F$ - 215.55 = K

b)

$\frac{9}{5}(180)$ - 215.55 = K

324 - 215.55 = K

108.45 = K
