What happens to the particles of a substance during condensation?

• A. They move freely and expand.
• B. They lose energy and get closer together.
• C. They move rapidly and gain energy.
• D. They transition from solid to liquid.

Answer: (B)

During condensation, particles lose energy as the substance transitions from a gas to a liquid. This loss of energy reduces the kinetic energy of the particles, causing them to slow down and come closer together. As a result, the arrangement of the particles becomes more ordered compared to their gaseous state, which is characterized by greater movement and separation. In contrast, the other processes described in the incorrect choices depict different states of matter or processes that do not align with the behavior of particles during condensation. For instance, the movement of particles that freely expands or transitions rapidly does not occur during condensation, as the process specifically involves a decrease in energy and a move towards a more compact arrangement. Additionally, transitioning from solid to liquid refers to melting, which is a distinct phase change involving different conditions and energy dynamics. Overall, the behavior of particles that lose energy and get closer together is the defining characteristic of condensation.
