Question

The solubility of a gas in a liquid decreases with the increase in temperature.

• A. True
• B. False

Answer 1

The correct option is A True

• As the temperature increases, the kinetic energy of molecules of gas increases.
• Attractive intermolecular interactions in the gas phase are essentially zero for most substances.
• When a gas dissolves, it does so because its molecules interact with solvent molecules.
• Because heat is released when these new attractive interactions form, dissolving most gases in liquids is an exothermic process.
• According to Henry's law states that, at a given temperature, the solubility of a gas in a liquid is proportional to the partial pressure of the gas above the liquid.
