Question

A tungsten light bulb filament may operate at 2900 K. What is its Fahrenheit temperature? What is this on the Celsius scale?

a) (4178.0ºF, 2422.0ºC)
b) (3918.0ºF, 2152.0ºC)
c) (3918.0ºF, 2422.0ºC)
d) (4178.0ºF, 2152.0ºC)

Answer 1

The Fahrenheit temperature of the tungsten light bulb filament operating at 2900 K is 4178.0 ºF and on the Celsius scale, it is 2422.0 ºC.

Step-by-step explanation:

To convert the temperature from Kelvin to Fahrenheit, we can use the formula:

F = (9/5)(K - 273.15) + 32

Substituting K = 2900 K into the formula, we get:

F = (9/5)(2900 - 273.15) + 32 = 4178.0 ºF

To convert the temperature from Kelvin to Celsius, we can use the formula:

C = K - 273.15

Substituting K = 2900 K into the formula, we get:

C = 2900 - 273.15 = 2422.0 ºC
