Question

At atmospheric pressure, the boiling point of water is ${100}^{\circ }C$. What would be the boiling temperature on the Fahrenheit scale?

• A.
  ${148}^{\circ }F$
• B.
  ${212}^{\circ }F$
• C.
  ${87}^{\circ }F$
• D.
  ${23}^{\circ }F$

Answer 1

The correct option is B

${212}^{\circ }F$
The rule for the conversion of temperature from degree Celsius to degree Fahrenheit is

$\frac{{}^{\circ }C}{5}=(\frac{{(}^{\circ }F-32)}{9}\frac{100}{5}=\frac{{(}^{\circ }F-32)}{9}\Rightarrow \text{Temperature in degree Fahrenheit is}(20\times 9)+32={212}^{\circ }F$
