The amount is up to you. Change the volume of the box, and heat or cool it as you like. If you accidentally blow the lid off, click the Return Lid button. In the data table, record the pressure (P), length (V), number of gas molecules (n), and temperature (T). Then click the reset button, change all of the variables, and again record the measurements

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).

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
