What is Liquid state to the solid state?

Liquid is like water in your sippy cup, and solid is like the ice cubes floating in it.

Think about your favorite toy car. The car itself is a solid. It keeps its shape whether it sits on the floor or rolls across the room. Now think about the water in your bath. It has no fixed shape. It moves to fill the whole tub. That is a liquid.

Imagine a box of LEGO bricks.

1. Solids are like LEGOs snapped tightly together. They stay in one specific shape. They do not squish or flow.
2. Liquids are like loose LEGOs in a bag. They slide past each other. They take the shape of whatever holds them.

Why does this happen? It is all about how fast the tiny building blocks of matter are moving.

When you heat a solid, those tiny blocks get wiggly. Eventually, they wiggle so much that they break their tight hold. They start to slide around. The solid turns into a liquid.

This is why ice melts into water. The heat gives the particles energy to move freely.

So, a liquid is just a solid that has relaxed its grip. It flows instead of staying stiff. Next time you drink juice, remember: those tiny juice particles are dancing and sliding past each other. That is the liquid state.
