Changes of state are physical changes in matter. They are reversible changes that do not involve changes in matters chemical makeup or chemical properties. They occur when matter absorbs or loses energy. Processes in which matter changes between liquid and solid states are freezing and melting. For a solid to change to a liquid, matter must absorb energy from its surroundings. Freezing happens when the water cools and loses energy until they remain in fixed positions as ice. Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation. Processes in which matter changes between solid and gaseous states are sublimation and deposition. | 0.279077 |

These three states include solid, liquid, and gas. Solid states of matter are rigid and have a fixed shape and fixed volume. They cannot be squashed. Liquid states of matter are not rigid and have no fixed shape, but have a fixed volume. They too cannot be squashed. Gas states of matter are not rigid and have no fixed shape and no fixed volume. This state of matter can be squashed. | 0.306284 |

A material will change from one state or phase to another at specific combinations of temperature and surrounding pressure. Typically, the pressure is atmospheric pressure, so temperature is the determining factor to the change in state in those cases. The names of the changes in state are melting, freezing, boiling, condensation, sublimation and deposition. The temperature of a material will increase until it reaches the point where the change takes place. It will stay at that temperature until that change is completed. Solids are one of the three phase changes. Their structure and their resistance to change their shape or volume characterize solids. In a solid, the molecules are closely packed together. Liquids are the next of the three phase changes. Liquids are very different from solids, their structure is a bit freer, but not as free as gas. In a liquid phase, the molecules will take the shape of its container or the object that it is in. Gases are the last of the three phase changes. A gas phase is one of the simpler phases, because the gas molecules are the freest. This is because theoretically the molecules behave completely chaotically and they roam anywhere and fill every space of an object or container. | 0.303643 |

Thats because state of matter is a physical property. As a result, when matter changes state, it doesnt become a different kind of substance. For example, water is still water whether it exists as ice, liquid water, or water vapor. | 0.70677 |
