Solid is one of the four fundamental states of matter (the others being liquid, gas, and plasma). In solids particles are closely packed. It is characterized by structural rigidity and resistance to changes of shape or volume. Unlike liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the ...
Gases become liquids; liquids become solids. On the other hand, increasing temperature and decreasing pressure allows particles to move further apart. Solids become liquids; liquids become gases. Depending on the conditions, a substance may skip a phase, so a solid may become a gas or a gas may become a solid without experiencing the liquid phase.
The solid angle of a face subtended from the center of a platonic solid is equal to the solid angle of a full sphere (4 π steradians) divided by the number of faces. Note that this is equal to the angular deficiency of its dual. The various angles associated with the Platonic solids are tabulated below.
If 127 parts of iodine, which is an almost black solid, and loo parts of mercury, which is a white liquid metal, be intimately mixed by rubbing them together in a mortar, the two substances wholly disappear, and we obtain instead a brilliant red powder quite unlike the iodine or the mercury; almost the only property that is unchanged is the weight.
Some solids, such as steel or concrete, are difficult to break, even if they are made to carry a heavy weight. This is because their particles are bound together very strongly. Such materials are said to have high strength and are used to construct bridges and buildings. Strength is a different property from hardness.
Solid definition is - being without an internal cavity. How to use solid in a sentence.
How are solids used in your everyday life? I live in a solid. I am sitting on a solid and am wearing solids. My eyesight is helped by solids as my fingers tap on different solids and I monitor the ...
solid - Uses of Solids - Solids can be hard (cement, for example) or soft (gold); brittle (eggshells), malleable (copper), or elastic (rubber); heavy (lead) or light (balsa wood). Some solids are good conductors of heat and electricity; others are insulators.Solid state physicists and chemists study the relationship between the structure of solids and their physical properties.
Solid is a state of matter in which the molecules are packed closely together and usually arranged in a regular pattern. A solid object has a fixed shape and volume.
