Problem 3
Q
1. “Room temperature” is often taken to be $68 ^\circ \textrm{F}$. What is this on the Celsius scale?
2. The temperature of the filament in a lightbulb is about $1900 ^\circ \textrm{C}$. What is this on the Fahrenheit scale?
A
$20^\circ\textrm{C, } 3500^\circ\textrm{F}$

VIDEO TRANSCRIPT

This is Giancoli Answers with Mr. Dychko. The temperature in degrees Celsius is 5/9 times the Fahrenheit temperature after you take away 32. So, 68 degrees Fahrenheit for room temperature minus 32 multiplied by 5/9 is 20 degrees Celsius. And then for the temperature inside a light bulb you take, the Fahrenheit temperature is calculated by going 5, or 9 over 5 times the temperature in Celsius and then add 32 after you do the multiplying. So, we have 9/5 times 1,900 degrees Celsius temperature of the filament plus 32. And that gives about 3,500 degrees Fahrenheit.

This should be degrees F for part b

Thanks a lot for noticing that ljn8, I've updated the text.

Cheers,
Mr. Dychko

Can you please include the formulas first rather than just plugging in the numbers?

Never mind. I read the question wrong.
