Question

The temperature of the filament in a lightbulb is about 1900∘C∘C. What is this on the Fahrenheit scale? Express your answer using two significant figures.

Answer 1

Answer:

Using two significant figures the temperature is $3.4\times10^{3}$ Fahrenheit

Explanation:

Fahrenheit and Celsius are different scales of temperature. The conversion between Fahrenheit and Celsius is:

$Fahrenheit\,degree=Celsius\,degree*\frac{9}{5} + 32$

So, for 1900 Celsius degree

$Fahrenheit\,degree=(1900)*\frac{9}{5} + 32$

$Fahrenheit\,degree=3452 F$
