In a conventional automobile, these energy transformations are involved: 1  Chemical energy in the fuel converted to kinetic energy of expanding gas via combustion. 2  Kinetic energy of expanding gas converted to linear piston movement. 3  Linear piston movement converted to rotary crankshaft movement.
Rhyolite is an extrusive igneous rock with a very high silica content. It is usually pink or gray in color with grains so small that they are difficult to observe without a hand lens.Rhyolite is made up of quartz, plagioclase and sanidine, with minor amounts of hornblende and biotite.Trapped gases often produce vugs in the rock. These often contain crystals, opal or glassy material.t is usually pink or gray in color with grains so small that they are difficult to observe without a hand lens.

Chrysolite is from the Greek chrysolithos meaning a precious stone of golden color. It comes from chryso meaning precious things made of gold, and lithos meaning of building stones. Peridot is the gemstone form of Olivine or Chrysolite and possesses a much richer green color. Mg-rich Olivine has been discovered in meteorites, on the Moon, and on Mars. Chrysolite and Olivine in general are a very abundant, but gem quality Peridot is rather rare.
