Q. The lower and upper fixed points of a faulty thermometer are $5^{\circ}$ and $99^{\circ}$ respectively. If the reading of the thermometer is $52^{\circ}$, the temperature on the Fahrenheit scale is :

Thermal Properties of Matter

Solution:

$\frac{\text { Reading of faulty thermomenter }-L F P}{U F P-L F P}=\frac{F-32}{180}$
$\frac{52-5}{99-5}=\frac{F-32}{180}$
$90=F-32$
$F=122^{\circ} F$
