Question

If the temperature of a liquid can be measured in Kelvin units as $xK$ or
in Fahrenheit units as $yF$, the relation between the two systems of
measurement of temperature is given by the linear equation

$y=\frac{9}{5}(x-273)+32$
Find the temperature of the liquid in Fahrenheit if the temperature of the liquid is $313K$.

• A. $33$
• B. $76$
• C. $104$
• D. $21$

Answer 1

Answer: (C)

$104$

Given linear equation is $y=\frac{9}{5}(x-273)+32$

Also given, temperature in Kelvin i.e. $x=313K$

We need to find temperature in Fahrenheit i.e.$y$.

$y=\frac{9}{5}(313-273)+32$

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

$\Rightarrow y=72+32$

$\Rightarrow y=104$
