Potential energy is defined as "stored" energy, which can take various forms, including elastic and gravitational potential energy. In the context of chemistry, potential energy relates to the intermolecular forces between particles. In gases, particles are spaced further apart compared to liquids, analogous to a stretched rubber band, indicating that gas particles possess higher potential energy. This is because the weak intermolecular attractions in gases can be likened to a rubber band that is stretched, while in liquids, the particles are closer together, resulting in lower potential energy. Understanding this concept helps clarify why gases have greater potential energy than liquids.
