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.

Petropedia explains Rhyolite. Rhyolite is considered equivalent to the plutonic granite rock. Due to the presence of Silica, Iron, and Magnesium, the melts of rhyolite are highly viscous and highly polymerized in nature. However, some of the substances cool quickly into crystals from natural gas. The following are some of its uses: 1  It is used in cement to strengthen the material which is used in constructing skyscrapers. 2  It is used as a cutting tool by the Maori. 3  It is used as a healing stone. 4  It is used in jewelry as a decorative stone.
