Understand the Problem

The question is asking for multiple-choice questions (MCQ) related to solutions, which could pertain to topics such as chemistry, biology, or general science. The user may be seeking a quiz or exam practice related to this subject area.

More Information

When a gas dissolves in a liquid, it generally releases heat, making the process exothermic. This is due to the formation of intermolecular attractions between the gas molecules and the liquid, which compensates for the energy required to separate gas molecules.

Tips

A common mistake is to assume that dissolution processes are always endothermic. However, in the case of gases dissolving in liquids, the process is typically exothermic.
