Question

Convert ${40}^{\circ }C$ on the​
a) Fahrenheit scale​
b) Kelvin scale.​

Answer 1

Given,
Temperature on Celsius scale$\left(C\right)={40}^{\circ }C$,
To find, Temperature on Fahrenheit scale $\left(F\right)$,
Temperature on Kevin scale ($K$).
As we know,
$\frac{C-0}{100}=\frac{(F-32)}{180}=\frac{K-273}{100}$
a) Converting ${40}^{\circ }C$ on Fahrenheit scale
$F=\frac{9}{5}C+32$

$F=\frac{9}{5}\times 40+32$

$F=72+32$
$F={104}^{\circ }F$

${40}^{\circ }C$ is equal to ${104}^{\circ }F$ on the Fahrenheit scale.

b) Converting ${40}^{\circ }C$ on Kevin scale

$K=C+273$
$=40+273$
$=313K$

${40}^{\circ }C$ is equal to $313K$ on the Kevin scale.
