Final answer:
Condensation is the process in which particles move closer together but remain in motion. The example of diffusion is the smell of cooking spreading through a house.
Step-by-step explanation:
The process in which particles move closer together but remain in motion is condensation. In this process, a gas or vapor cools and converts into a liquid state, causing the particles to come together while still having kinetic energy.
The example of diffusion among the given options is d) The smell of cooking spreads through a house. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. In this case, the smell molecules spread and mix evenly in the air of the house.
