solid.
In a solid state of matter, particles are closely packed and can only vibrate in place. They have a fixed position and cannot move around freely like in liquids and gases.
A solid is a state of matter that does not change in volume because the particles are closely packed together and have fixed positions.
We can determine the state of matter by observing how closely its particles are connected. In solids, particles are closely packed and do not move freely. In liquids, particles are close but can move past each other. In gases, particles are far apart and move freely.
Matter changing state is usually a result of the material changing temperature and/or a change in the surrounded pressure on the material. The change of state is usually associated with a change in its density.
The matter with a shape and volume that don't change is in a solid state. Solids have a fixed shape and volume because their particles are closely packed together and vibrate in place.
The energy levels for the states of matter are different. In solids, particles have the least energy and are closely packed together in a fixed position. In liquids, particles have more energy and are able to move around but are still close together. In gases, particles have the most energy and are far apart and move freely.
The measurement of how closely particles are packed together is usually by state of matter. Gasses are measured as have particles that are further apart than liquids or solids for example.
In a solid, particles vibrate in place due to thermal energy. Even though they do not change position on a macroscopic scale, they continuously move at the microscopic level, resulting in a state of perpetual motion within the solid material.
During a physical change, the matter remains the same, but the arrangement and position of the particles within the object may change. This can involve processes like melting, freezing, or evaporating, where the particles gain or lose energy to shift from one state to another while still maintaining their identity.
The state of matter is determined by the arrangement and movement of its particles. In a solid, particles are closely packed and vibrate in fixed positions. In a liquid, particles are close together but can move around each other. In a gas, particles are far apart and move freely.
The state of matter that can change its size depending on the container is gas. Gas particles are not held together closely and move freely within the container, allowing them to expand or contract to fill the available space.
In a solid state, particles move the slowest and are closely packed together. This results in a fixed shape and volume for solids.
