Hi my name is Sonny and i'm gonna preform some magic with help from the sun.
This ice cube represents a solid, in which the particles are tightly packed together, has a definite shape and volume, and the interaction of particles is very strong. The motion of its particles is they can only vibrate, and also for its fluidity, it can't flow.
The reason the ice becomes a liquid is because of the sun, the heat causes the ice cube to melt into water.
Now the solid is a liquid, it takes the shape of its container, has a definite volume, the particles are further apart, but still, have a strong bond, the particles move around each other and they can flow.
Wow it's getting really hot out here now! The water is becoming a gas because of the heat of the sun, it causes the water to become a gas called water vapor.
A gas takes the shape of its container, has a indefinite volume, has loosely packed particles. there is little interaction between the particles, the particles move quickly, and gas flows.
