You are shopping for a new car. Compare the volume of carbon dioxide gas emitted by a luxury sedan and a Hummer during a 265 miles trip, if the weatherman reported a temperature of 28°C and an atmospheric pressure of 732 mm Hg. The car dealer claims than the fuel efficiency is 31.2 miles per gallon of gasoline for the luxury car, 10.5 miles per gallon of gasoline for the Hummer. The major component of gasoline is octane (C8H18) which has a density of 0.71 g/mL.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
