Which of the following best explains why intermolecular forces between particles in a liquid phase are generally stronger than those between particles of the same substance in the gas phase?
(a) Because the temperature of a liquid is usually lower than that of the gas, the slower-moving particles experience stronger attractions.
(b) Hydrogen bonds can form only when the substance is in the liquid phase, so the attractions become much stronger.
(c) The average separation between particles is smaller in the liquid, allowing attractive forces to operate over shorter distances.
(d) External pressure on a liquid compresses the particles, increasing the strength of the attractive forces.
