Think about the problem of aerodynamic heating. How does radiation andradiative heat transfer play a role in how hot a surface gets during re-entry? Why isthe bottom of the space shuttle black in color, but the top of the space shuttlewhite? Why are many spacecraft components wrapped in gold or silver foil insteadof painted a certain color?

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
