Brief Answer: A crystal is a regular arrangement of atoms or molecules but a solid may have a regular arrangement or a more random positioning of its constituents. All crystals are solids but not all solids are crystals. One normally makes the distinction clear with the terms crystalline solid and noncrystalline solid.
All solids are a collection of atoms and molecules, but not all solids have these atoms and molecules in a regular arrangement. When such regularity is present, it is properly called a crystal.
In solids the particles are in a fixed position, though vibration is present as a result of thermal motion. In a liquid or gas, particles move as a consequence of the thermal motion. In a solid, the forces between particles are strong enough to hold them in place.
The obvious examples of crystals one normally has experience with include simple table salt, diamonds and ice. (These normally have a highly regular atomic arrangement, but of course there is some distinction between an ideal perfect crystal and one with impurities and cracks. Nonetheless, at the atomic level, the crystalline arrangement is highly regular.)
The obvious examples of noncrystalline solids includes such things as glass, wood, bone and plastic. Actually, most everyday solids are noncrystalline. It is often true that apparently amorphous things like rock actually contain some microscopic crystals so one can not say always from outer appearances that something has no crystals at all inside.
Like most broad classifications, there are exceptions and special cases. Quasicrystals and liquid crystals are two examples of materials which have unusual structures and are the subject of scientific study.
What else can I help you with?
What is occilation motion?
Oscillatory motion is a repetitive back-and-forth movement around a central point or equilibrium position. It is characterized by a regular pattern of swings or vibrations, such as those seen in a pendulum or a vibrating guitar string.
What is the state of matter with particles vibrating in a fixed position?
Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available.
In which state particles held together but may move?
Particles may be held together in a solid state, where they maintain a fixed position in a regular arrangement but may still vibrate in place.
Are the particles in a regular arrangement?
Yes, particles in a solid are typically arranged in a regular and repeating pattern. This ordered arrangement is what gives solids their definite shape and volume.
Phase of matter with definite shape and volume in which the particles are arranged in a regular repeating pattern?
No, a phase is a physical characteristic. The substance may or may not have definite shape and volume.
A substance is made up of constantly vibrating particles arranged in a regular geometric pattern This substance is a?
Solid. Most likely a crystalline.
The Particles in a Solid are?
The particles are vibrating about their mean position.
What happens to the particles of a solid it becomes a liquid?
The molecules in the individual solid particles break free of their regular rigid framework by vibrating more energetically. Eventually the particles of the solid lose their shape and fuse together as a pool of liquid.
What happens to particles of matter as they change from a solid to a liquid?
It changes shape.
A liquid substance _______. A. has particles packed tightly together B. has definite volume C. has definite shape D. has particles arranged in a regular pattern?
B. has definite volume
What is occilation motion?
Oscillatory motion is a repetitive back-and-forth movement around a central point or equilibrium position. It is characterized by a regular pattern of swings or vibrations, such as those seen in a pendulum or a vibrating guitar string.
Does a solid forms when the average energy of a substance's particles decreases then increases?
Yes, a solid forms when the average energy of a substance's particles decreases below a certain point (reaching a critical temperature known as the freezing point), causing the particles to arrange into a regular, fixed pattern. After this point, any increase in average energy would not typically turn the substance back into a solid unless it exceeds the melting point and the particles regain enough energy to break free from their fixed positions.
What is the state of matter with particles vibrating in a fixed position?
Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available.
If a substance besides water is changed from a gas to a liquid and then to a solid what happens to the particles?
When a substance changes from a gas to a liquid to a solid, the particles transition from being far apart and moving freely in a gas to closer together but still able to slide past each other in a liquid, and finally tightly packed in a regular pattern in a solid. The energy of the particles decreases as they transition from gas to liquid to solid.
How would you know if the substance is a solid?
A substance is a solid if it has a definite shape and volume, and maintains its shape under normal conditions of temperature and pressure. Solids are rigid and have tightly packed particles arranged in a regular pattern. They do not flow like liquids or gases.
In which state particles held together but may move?
Particles may be held together in a solid state, where they maintain a fixed position in a regular arrangement but may still vibrate in place.
Are crystalline and amorphous solids?
Crystalline Solids are when the particles form a regular repeating pattern. Amorphous solids have particles that are not arranged in a regular pattern.
