Gases and plasmas have neither definite shapes nor definite volumes. They both expand to fill available space, and can be reshaped by their containers. Liquids have definite volume, while solids have both definite shape ... More »

Solids maintain a definite shape and volume because their atoms are tightly bound to each other. Solids can be crystalline or amorphous. In crystalline solids, such as ice and metal, atoms are arranged in a regular geome... More » Science Physics Motion & Mechanics

The state of matter called a solid does have a definite volume and shape. This is one of the properties that defines a solid. Some other properties pertaining to a solid are that the molecules within a solid are packed t... More »

Gases and plasmas undergo changes in volume most easily. In contrast, liquids and solids have fixed volumes, although liquids do not have fixed shapes. Gases and plasmas expand or contract to fill their containers. More »

The five phase changes of matter are solids, liquids, gases, plasmas and Bose-Einstein condensates. Elements are able to move between these phases when certain physical conditions exist. More »

The five states of matter include Bose-Einstein condensates, solids, liquids, plasmas and gases. Matter is anything that occupies space and has weight. Matter may change its state when energy is increased or decreased. More »

Solids have definite shapes and volumes because their atoms and molecules are held together firmly by the strong inter-molecular forces. At low temperatures, the kinetic energy in the solid is usually not enough to overc... More »
