Question

The melting point of ethyl alcohol is -129 F. What is the Celsius reading?

Answer 1

We are asked to convert -129 F to Celsius. To do that we will use the following formula:

`C=(5)/(9)(F-32)`

Where:

`\begin{gathered} C=\text{ reading in Celsius} \\ F=\text{ reading in Fahrenheit} \end{gathered}`

Now we plug in the reading in Fahrenheit:

`C=(5)/(9)(-129-32)`

Solving the operations:

`C=-89.44\text{Celsius}`

Therefore, the Celsius reading is -89.44°C.
