1- An isolated closed pressured gap inside earth caused organic materials to transform and produce oil and gas form
2- Fire force internal gases to come out to produce more fire and heat
3-Keeping heat and cool inside your home
4- Either vapor or electrons
5- The term "photovoltaic" comes from the Greek phos meaning "light", and the name of the Italian physicist Volta, after whom the volt (and consequently voltage) are named. It means literally of light and electricity.
The photovoltaic effect was first recognised in 1839 by French physicist Alexandre-Edmond Becquerel. However it was not until 1883 that the first solar cell was built, by Charles Fritts, who coated the semiconductor selenium with an extremely thin layer of gold to form the junctions. The device was only around 1% efficient. Russell Ohl patented the modern solar cell in 1946 (US2402662, "Light sensitive device"). Sven Ason Berglund had a prior patent concerning methods of increasing the capacity of photosensitive cells.

I only know one, and not in a scientific phrasology sort of way...#3...Insulation is used to create a barrier between the walls of a home to keep temperatures inside as constent as possible. If fiberglass it is made by layering thin threads of spun glass on top of each other, trapping air pockets between the layers. It's these air pockets that do the insulating. They seperate hot and cold air, just like insulation in wiring keeps the electricity coursing down the wire from getting outside and shocking someone(or keeping things from touching a hot wire). The thicker the insulating material, the more air pockets, hence more insulating strength. When its warm inside and cold outside, the warm airs doesn't travel as fast to the outside (remember that heat flows to a cooler area). When it's cooler inside and warmer outside, heat from outside doesn't flow so fast into the cool home. Many years ago, before fiberglass and asbestos or other modern insulators, people found that if they lined their home with papers layers on top of each other, they had better climate control than when they plastered their walls with mud or any traditional packing materiel that was dense, and eventually learned that it was the air between the layers that did the work.
