Thermometry & Thermal Expansion

A celsius and a Fahrenheit thermometer are dipped in boiling water. The temperature of water is lowered until the Farenheit thermometer shows $140^\circ$ . What is the fall in temperature on the Celsius thermometer?

Show answer and solution

Answer: (b)

Boiling water: $100^\circ$ C. At $140^\circ$ F: $C=\frac{5}{9}(140-32)=60^\circ$ C.
Fall $=100-60=40^\circ$ C
So the answer is (b) $40^\circ$ C.
