According to the kinetic molecular theory, how is condensation explained?

• A. Condensation happens when gas particles collide more frequently, causing them to break apart into smaller particles.
• B. As gas particles lose kinetic energy, their motion slows, allowing intermolecular forces to pull them together into a liquid.
• C. Condensation occurs because gas particles gain energy and move farther apart, forming a liquid.
• D. Condensation is explained by the complete absence of intermolecular forces between gas particles.

Answer: (B)

Verified step by step guidance

1. Recall that the kinetic molecular theory describes the behavior of particles in different states of matter, focusing on their motion and energy.
2. Understand that condensation is the process where a gas turns into a liquid, which involves a change in the energy and movement of gas particles.
3. Recognize that gas particles have high kinetic energy, moving rapidly and far apart, which keeps them in the gaseous state.
4. During condensation, gas particles lose kinetic energy, which means their motion slows down.
5. As the particles slow, intermolecular forces become significant enough to pull the particles closer together, resulting in the formation of a liquid.
