A gas is confined in a rigid container at a certain pressure . The amount of gas in the container and the absolute temperature are both doubled while the volume of the container is cut in half . How does the new pressure of the gas compare to the original pressure ? Will it double, quadruple, six times more, or eight times more?

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).
