Final answer:
According to the kinetic-molecular theory, when a liquid is poured into another container, the volume increases to fill the new container, but the shape stays the same.
Step-by-step explanation:
According to the kinetic-molecular theory, when a liquid is poured into another container, the volume increases to fill the new container, but the shape stays the same. This is because the particles of a liquid are close together but not tightly packed, allowing them to flow and take the shape of their container. However, they are still attracted to each other, so the volume expands to fill the new container.
