100 grams of molten lead (600°C) is used to make musket balls. If the lead shot is allowed to cool to room temperature (21°C), what is the change in entropy (in J/K) of the lead? (For the specific heat of molten and solid lead use 1.29 J/g/°C; the latent heat of fusion and the melting point of lead are 2.45 × 10^4 J/kg and 327°C.)

A) is produced by the action of solar radiation and atmospheric atoms. B) consists of ozone ions. C) reflects solar ultraviolet and atmospheric atoms. D) occurs at roughly the same altitude as high clouds.
How is the energy that powers radio galaxies, quasars, and other active galactic nuclei produced?
A) by matter that has been converted to pure energy by interacting with the jets shot out by a central black hole B) by nuclear fusion near a central black hole C) by matter-antimatter annihilation near a central black hole D) by magnetic fields that trap and accelerate charged particles, which then radiate large amounts of energy E) by gravity, which converts the potential energy of matter falling toward a central black hole into kinetic energy, which is then converted to thermal energy by collisions among the particles of matter
