Which of the following factors affects the solubility of a gas in a liquid solvent?

• A. Molar mass of the solvent
• B. Color of the gas
• C. Shape of the container
• D. Temperature of the solvent

Answer: (D)

Verified step by step guidance

1. Understand that the solubility of a gas in a liquid is influenced by physical factors that affect how gas molecules interact with the solvent.
2. Recall Henry's Law, which states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid and inversely affected by temperature.
3. Recognize that temperature affects solubility because increasing temperature generally decreases the solubility of gases in liquids due to increased kinetic energy causing gas molecules to escape more easily.
4. Identify that molar mass of the solvent, color of the gas, and shape of the container do not significantly affect the solubility of the gas in the liquid.
5. Conclude that among the given options, the temperature of the solvent is the key factor affecting the solubility of a gas in a liquid.
