How does the solubility of gases in liquids change with an increase in temperature, and what is the reason for this change?

Options

  1. ASolubility increases with increasing temperature due to the absorption of heat.
  2. BSolubility remains constant with temperature changes.
  3. CSolubility decreases with increasing temperature because dissolution is an exothermic process.
  4. DSolubility decreases with increasing temperature due to the endothermic nature of dissolution.

Correct answer

C. Solubility decreases with increasing temperature because dissolution is an exothermic process.

Step-by-step solution

The paragraph explains that the solubility of gases in liquids decreases with an increase in temperature because the dissolution process is exothermic.
