A mechanical wave can transfer energy by vibrating particles of matter. Mechanical waves require a medium, such as air or water, to travel through, and they transmit energy through the periodic motion of particles in the medium. Examples include sound waves and seismic waves.
Particles of matter have mass, which determines their weight and affects their interactions with other particles. Particles of matter have volume, which determines the amount of space they occupy. Particles of matter are constantly in motion, vibrating or moving within a substance.
Conduction.
No, not all sounds are made by vibrating objects. For example, the sound of a thunderstorm or an explosion is not produced by a vibrating object.
The particles in air that are pushed closer together as a result of being near something that is vibrating are called compressions. These areas of higher pressure travel through the air as sound waves.

Particles that make up matter are in constant motion. This motion can be translational (moving from one place to another), vibrational (vibrating in place), or rotational (spinning around an axis). This motion is a result of the internal energy of the particles.

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.

constant motion. They are constantly vibrating and moving, even though they may appear still to the naked eye. This motion is due to the kinetic energy of the particles.
In solids, particles are tightly packed, vibrating in fixed positions. In liquids, particles are more spread out and can move past each other. In gases, particles are widely separated and move freely in all directions.
sound is mainly caused by vibrating particles and matter consists of matter and the 3 states of matter are solids liqiuids and gasses and due to the way particles are spaced in the different states of matter we will have sounds travelling at different speeds as it crosses the different states of matter.
The particles stay rigid in all states.
