What happens if you decrease the kinetic energy of a substance? what would happen if you increased the kinetic energy of a substance?

Decreasing the kinetic energy of a substance would cause that substance's molecules to move slower. Increasing the kinetic energy would cause the substance's atoms to move faster, and melt, evaporate, or etc.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this
