A liquid is a state of matter where particles have enough energy to move around each other but are still close together. This allows liquids to flow and take the shape of their container, like water or juice.

• A) Solid: Particles in solids are tightly packed and don't move freely. Solids keep their shape.
• B) Gas: Particles in gases are far apart and move quickly, filling any space.
• D) Plasma: Plasma has very energetic particles, but it's not something we see often in daily life.

So, liquids flow and take the shape of their container but don’t spread out like gases!
