If A Surface Emits 200 W At A Temperature Of T, How Much Energy Will It Emit At A Temperature Of 2t? |
|
Answer» Since E u T4, a 2-fold INCREASE of temperature brings a (24) = 16-fold increase in ENERGY. Thus the surface will EMIT (16)(200) = 3200 W. Since E u T4, a 2-fold increase of temperature brings a (24) = 16-fold increase in energy. Thus the surface will emit (16)(200) = 3200 W. |
