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.

Rhyolite is a very fine-grained to glassy extrusive igneous rock (i.e., volcanic), usually light in colour but not always, consisting essentially of quartz (silica) and alkalic feldspar. It is the extrusive equivalent of granite. medium-to coarse-grained intrusive igneous rock composed of potassium-and sodium-rich feldspar, quartz, minor plagioclase, and small amounts of ferromagnesian minerals such as biotite or hornblende. It is the intrusive equivalent of rhyolite.
