Answer:
Solar-powered photovoltaic (PV) panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business. (Electrical Energy)

<span>This is the process of radioactive dating. Carbon is used because it is an essential part of all living organisms and has a radioisotope that decays with a half-life of 5000 years. This ratio makes it easy to date an object using Carbon-14. Uranium is used for objects that have a much longer half-life, outside the bounds of carbon's abilities.</span>
The answer would be: a "Chemical change."
One of the indicators of a chemical change is a change in color. This is seen in rusting metal. When exposed over time to air, metal changes color. The substance composition has changed through the breaking of bonds and formation of new bonds.

Yes. Compounds can have different properties than the elements that go into them.
EXAMPLE: water is a polar liquid, while pure hydrogen and pure oxygen are both nonpolar gasses.
