8. What causes matter to change phases?
Your answer

Increase or decrease in kinetic energy of the molecule of the matter

Explanation:

As the kinetic energy of the

Matter increases, solid can change to liquid or liquid to gas and meaning heat energy is added, also as kinetic energy of the molecules of matter decreases,heat energy is removed and gas change to liquid or liquid to solid as the case may be

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).
