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 an igneous rock in the class designated as  felsic  rock. This class of rock crystallizes from silicate minerals at relatively low temperatures and with relatively a high percentage of silica.It is at the low temperature extreme of the Bowen reaction series.hyolite is much less common than granite, but there are large lava flows and deposits of rhyolite in Yellowstone Park, Wyoming, USA. These rhyolite formations are along the Snake River in Hell's Canyon on the Idaho-Oregon border.
