It depends on what you mean by "pass through."

* At a microscopic level: Solids are made of tightly packed molecules, while liquids have more freedom of movement. This means a liquid molecule could potentially squeeze through a gap too small for a solid molecule. So, in this sense, a liquid might "pass through" something a solid couldn't.

* In everyday terms: We usually think of solids as having a fixed shape and liquids as being able to flow. In this sense, liquids can pass through openings that solids can't. For example:

* A sieve: Water can pass through the holes in a sieve, but a rock won't.

* A straw: You can drink liquid through a straw, but you can't push a solid object through it.

* A filter: Filters are designed to let liquids pass through while blocking solids.

The key difference is the rigidity of the solid. Solids have a fixed shape and are resistant to deformation, making it difficult for them to squeeze through small openings. Liquids, on the other hand, can flow and take the shape of their container, allowing them to move through narrow passages.
