Problem

A flat ceramic tile of area

0.040\,\text{m}^2

is initially at

1200\,\text{K}

and cools linearly to

600\,\text{K}

over the next

4.0\,\text{min}

. Treat the tile as an ideal blackbody. Determine the total energy the tile emits during the

4.0\,\text{min}

cooling period. Use

\sigma = 5.67 \times 10^{-8}\,\text{W}\,\text{m}^{-2}\,\text{K}^{-4}
