Question

question:
a celsius thermometer indicates a temperature of 20 °c. whats the equivalent temperature on the fahrenheit scale?

answer options:
select one of four
293 °f \t\t\t20 °f
52°f \t\t\t68 °f

Explanation:

Step1: Recall the conversion formula

The formula to convert Celsius to Fahrenheit is $F = \frac{9}{5}C + 32$, where $C$ is the temperature in Celsius and $F$ is the temperature in Fahrenheit.

Step2: Substitute the given value

We are given $C = 20^\circ\text{C}$. Substitute this into the formula: $F=\frac{9}{5}\times20 + 32$.
First, calculate $\frac{9}{5}\times20$. $\frac{9}{5}\times20 = 9\times4 = 36$. Then add 32: $36 + 32 = 68$.

Answer:

68 °F
