B.
radiation.

radiation.

Explanation:

Radiation is a method of energy transfer in which energy can transfer through matter or through empty space. In this example, solar energy travels through empty space from the Sun, through the Earth's atmosphere, and to the metal surface. The metal surface absorbs some of the energy, which causes the surface to heat up.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
