Question

What is the temperature $32$ degree Fahrenheit in Degree Celsius?
A) $10$
B) $0$
C) $- 32$
D) $273$

Answer 1

We have to remember that $32^\circ F$ is the temperature at which distilled water which is in pure form freezes itself. Pure water boils at $212^\circ F$ or $100^\circ C$. These two are the scales at which one can measure the temperature.

Complete step by step answer:
We can start by knowing this,
Temperature can be measured using two scales. One is the Fahrenheit scale that is usually used in the U.S and the other is the Degree Celsius scale which is mostly used in India and other countries.
Temperature can be measured in degrees.
Fahrenheit can be written as $F$ whereas Degree Celsius can be written as $C$.
Generally a relationship between $F$ and $C$ can be represented as follows:
$F = C \times 1.8 + 32$
So, using this relationship it is easy to get the question solved.

Option A) is incorrect since using this formula we get some different value which is not $10$ thus, this is not a correct option.
Option B) Putting the values in the equation,
$F = C \times 1.8 + 32$
Given, $F = 32$
Now we can substitute the known values in formula we get,
$32 = C \times 1.8 + 32$
$32 - 32 = C \times 1.8$
On simplification we get,
$C = 0$
This is a correct option.
Option C) is incorrect since using this formula we get some different value which is not $- 32$ thus, this is not a correct option.
Option D) is incorrect since using this formula we get some different value which is not $273$ thus, this is not a correct option.

Hence, the correct answer is Option B.

Note: The values given in the question should be used carefully, one must read the question twice before solving to know what is actually asked, to get the value for Fahrenheit or Degree Celsius, as this formula $F = C \times 1.8 + 32$ is used.
