A centigrade and a Fahrenheit thermometer are dipped in boiling water. The water temperature is lowered until the Fahrenheit thermometer resisters $$140^0$$. What is the fall in temperature as registered by the Centigrade thermometer?

A$$30^0$$
B$$40^0$$
Correct Answer
C$$60^0$$
D$$80^0$$

Solution

The relation between Fahrenheit and centigrade scale is given by,
$$C=\dfrac{5}{9}(F-32)$$
Here , $$F=140$$ so $$C=(5/9)(140-32)=(5/9)(108)=60$$
Temperature in centigrade scale of boiling water is $$100^{\circ}C$$
So, fall in temperature $$=100-60=40^{\circ }C $$
