What are two states of matter?
Solids are objects with a fixed shape and volume, such as a rock or an ice cube. Liquids have no fixed shape but a constant volume, like water or juice. Both solids and liquids can be changed into different states by adding or taking away heat.
Solids and Liquids
Solid - A solid is a state of matter in which the molecules are packed tightly together and do not move around. Liquid - A liquid is a state of matter in which the molecules have room to move around. Melting and Freezing - Melting is the process of a solid turning into a liquid, and freezing is the process of a liquid turning into a solid.
The properties of solids and liquids can be used to identify them. For example, a solid has its own shape and a liquid has no shape. The molecules of solids are held in place by strong forces and the molecules of liquids are not held in place by any forces. The particles of a liquid are able to move and flow around each other, while the particles of a solid cannot move and flow around each other.
