It means that they move to and fro. The "particles" refer to the atoms or molecules of the solid. It is a well-known fact that all matter - whether solid, liquid, gas, or most other states of matter - is made up of atoms.
In a solid, particles are tightly packed together in a fixed arrangement, vibrating in place. In a gas, particles are widely spaced apart and move freely in random directions at high speeds.
The solid phase of matter typically has particles moving the slowest compared to the liquid and gas phases. In a solid, particles are closely packed and have limited mobility, resulting in slower movement and vibrating in fixed positions.
The particles in solids move back and forth in place. This is due to the vibrating motion of the particles within a fixed position in a solid structure.
When a solid is heated but not melted or burned, the particles within the solid start vibrating more rapidly due to the increase in temperature. This increased vibration increases the kinetic energy of the particles, causing them to move around more within their fixed positions in the solid's structure.
The solid phase of matter typically has the strongest attraction between particles, as they are closely packed and held together by strong intermolecular forces. This results in particles vibrating in fixed positions, which gives solids a definite shape and volume.
Particles are vibrating rapidly.
A solid. In a solid, particles are closely packed and have limited movement, vibrating in place without much freedom to roam.
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.
Sound is a pattern of vibrating particles of matter; these particles are necessarily in the form of a solid, liquid, or gas. If there are no particles of matter (in other words, a vacuum) then there will be no pattern of vibrations, since there is nothing to vibrate. Electromagnetic waves (such as light) are different. They are still generated by vibrating particles (usually electrons) but they do not consist of vibrating particles, but of electromagnetic fields. That is why they, unlike sound, can travel even in a vacuum.
Particles of a solid have the least amount of energy and are locked into place, although they are still vibrating with what little energy they have.
In a solid, particles are tightly packed together in a fixed arrangement, vibrating in place. In a gas, particles are widely spaced apart and move freely in random directions at high speeds.
matter with a definite shape and volume and has tightly packed particles that move mainly by vibrating
Solid. Most likely a crystalline.
The solid phase of matter typically has particles moving the slowest compared to the liquid and gas phases. In a solid, particles are closely packed and have limited mobility, resulting in slower movement and vibrating in fixed positions.
The particles in solids move back and forth in place. This is due to the vibrating motion of the particles within a fixed position in a solid structure.
