Verified step by step guidance

Understand the relationship between temperature and solubility for gases: As temperature increases, the kinetic energy of gas molecules increases, causing them to escape from the liquid more easily, thus decreasing solubility.

Understand the relationship between temperature and solubility for solids: For most solids, increasing temperature increases solubility because the added heat provides energy to break intermolecular forces in the solid, allowing more solute to dissolve.

Identify the pattern: Gases generally become less soluble with increased temperature, while most solids become more soluble.

Match the patterns to the options provided: The correct pattern is 'decreases, increases' for gases and solids respectively.

Select the correct answer based on the pattern: Option C ('decreases, increases') matches the observed behavior of gases and solids with temperature changes.
