Question

A sphere radiates energy at a rate of 2.00 J/sJ/s when its temperature is 100∘C∘C. At what rate will it radiate energy if its temperature is increased to 200∘C∘C? (Neglect any heat transferred back into the sphere.)

Step 1

According to the Stefan-Boltzmann law, the power radiated by a black body is proportional to the fourth power of its absolute temperature (in Kelvin). The formula is given by: \[ P = \sigma A T^4 \] where \( P \) is the power (energy per unit time), \( \sigma \) Show more…
