You place a sealed flask containing 2.5 grams of gas inside a freezer/ Explain what happens to the speed of the gas particles.

Decreases.

Explanation:

The speed of the gas particles in the sealed flask in question here will decrease as it enters the freezer because the motion of the gas particles will slow down.

Based on the kinetic molecular theory of gases, the temperature of the gas is a measure of the average kinetic energy of the molecules.

Since the freezer makes substances cool and temperature drops, the kinetic energy of the gases will substantially drop. Kinetic energy is the energy due to the motion of a body.

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).
