Question

The boiling and freezing points of water are exactly _____ degrees apart on the Fahrenheit scale.
1. 180
2. 273
3. 100
4. 50

Answer 1

Correct Answer - Option 1 : 180

The Correct Answer is 180.

• 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).
