Answer 1

The Correct Answer is 180.

Key Points

The boiling and freezing points of water are exactly 180 degrees apart on the Fahrenheit scale.
The freezing point of water is 32°F on the Fahrenheit scale and the boiling point is 212°F (at standard atmospheric pressure).
This puts 180 degrees apart from the boiling and freezing points of water.
Thus, a degree on the scale of Fahrenheit is 1⁄180 of the distance between the freezing point and the boiling point.
The freezing and boiling points of water on the Celsius scale are 100 degrees apart.
- 1°F temperature interval is equal to a 5⁄9 degrees Celsius interval.
- At -40 ° (i.e. −40 °F = −40 °C), the Fahrenheit and Celsius scales converge.
Absolute zero is -273.15 °C(-459.67 °F).

Additional Information

Boiling Point:
- The boiling point is the temperature at which the vapour pressure of a liquid becomes equal to atmospheric pressure and it converts from liquid to a gaseous state.
- It is different at different altitudes.
- The boiling point of water under normal conditions is 100° C.
- The boiling point usually decreases at high altitudes. So at high altitudes, the boiling point of water is less than 100° C.
