A centigrade and a Fahrenheit thermometer are dipped in boiling water. The water temperature is lowered until the Fahrenheit thermometer registers 140°. What is the fall in temperature as registered by the Centigrade thermometer?
-
- 80°
- 60°
- 40°
- 30°
Correct Option: C
| Using | = | ||
| 180 | 100 |
| ⇒ | = | ||
| 180 | 100 |
⇒ C = 60
Temperature of boiling water = 100°C
We get, fall in temperature = 100 – 60 = 40°C
