How much heat is absorbed by a 74g iron skillet when its temperature rises from 7oC to 28oC?

Physics

5 0
The specific heat of iron (assuming the skillet is pure iron) is 0.45 J/g-C. Then we use the equation q = mc(dT) to determine the total heat absorbed. This gives:
q = (74 g)(0.45 J/g-C)(28 - 7 C) = (74)(0.45)(21) = 699.3 J

how much energy must be transferred to a normal incandescent bulb (efficiency 0.05) for it to transfer 9J of energy by light?
oksian1 [2.3K]

Answer:

Revise energy transfers and use sankey diagrams to calculate the efficiency of these conversions with BBC ... Efficiency is a measure of how much useful energy is converted. Part of ... This is the Sankey diagram for a typical filament lamp: 100 joules of electrical energy is converted to 10 joules of light energy and 90 joules.
