Question

What is the reason that the liquid can flow?

A. The molecules are tightly packed.
B. The molecules are free to move, detached from each other.
C. The molecules are loosely packed and can slide past each other.
D. The molecules can convert into gas easily

Answer 1

Liquids are able to flow because their molecules are loosely packed and can slide past each other, allowing them to assume the shape of their container.

Step-by-step explanation:

The reason that liquids can flow is because their molecules are not tightly packed in a fixed position. Instead, the molecules in a liquid are loosely packed and have the ability to move past or slide over one another. This characteristic allows liquids to assume the shape of their container. Additionally, though liquids have attractive forces between their particles, these forces are not strong enough to keep neighboring molecules in a fixed position. Therefore, liquids are not easily compressed, possess a definite volume, and can be poured to match the shape of their containers.
