In a pressure cooker, a lid is screwed tightly onto a pot so that the air pressure in the pot is increased. what effect, if any, will this have on the boiling point of water in the pot? a) the boiling point will be raised. b) the boiling point will be lowered. c) the boiling point will be unaffected. d) none of the above.

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).
