Question

What is the total amount of energy emitted by an object with a temperature of 134°F? HINT: convert to degrees Kelvin before applying to the formula and round answer to the nearest tenth

Answer 1

Hi Jane D.,

Sorry, no can do! The Stefan-Boltzmann law applies to radiation from a "black-body" surface, per unit area, with an emissivity of 1 across the spectrum. Since you refer to a specific object (apparently) without giving details of the area of its radiating surface or its emissivity data, you have an undetermined condition. I suppose you could give your answer in terms of (Stefan-Boltzmann radiation per unit surface area) "* Surface_area * Emissivity". I reckon you have the desired expression for that first term in hand?
