Question

How much heat (Btu) is prod uced by a 150-W light bulb that is on for 20-hours?

Answer 1

Answer:

heat produced by 150 watt bulb is 510 Btu

Explanation:

Given data:

Power of bulb is 150 W

Duration for light is 20 hr

We know that 1 Watt = 3.4 Btu

hence using above conversion value we can calculate the power in Btu unit

so for $150 W\ bulb = 150\times 3.4 = 510 Btu$

therefore, 150 W bulb consist of 510 Btu power for 20 hr

output heat by 150 watt bulb is 510 Btu
