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.

Answers. Best Answer: Rhyolite is extrusive. Rhyolite is a relatively common volcanic rock. It is the chemical equivalent of granite. Although the two rock types have the same chemistry, rhyolite is extrusive and granite is intrusive.hile granite has crystals that are generally easy to see, in rhyolite the crystals are often too small to see. This is due to the more rapid cooling of the rhyolite lava compared to granite's slower cooling magma. I hope this helps you.
