 Shape up:
All solid substances has a definite shape and volume. The particles in a solid are fixed positions and are close together. A solid can´t easily change in shape or volume. You can change the shape of a solid by breking it into pieces.






the water would take the shape of the container. The water would have the same volume as the container. All liquids have a definitive volume but no definite shape. The particles in a liquid are close together, but they are not tightly attached to one another. 



Gases do not have a definite volume or shape. The particles in a gas are very far apart compared to the particles in a solid or a liquid. The amount of space between the particles in a gas can change more easily.
