Want this question answered?
Particles do not move faster in a vacuum. Particles move faster when the temperature increases.
The entire electromagnetic spectrum can move through a vacuum.
how electron move in vacuum and not move in air
space is a vacuum, and sound can't move through a vacuum.
No, they cannot. Sound waves are compression waves (mechanical longitudinal waves). This means they travel through mediums with the particles of the medium vibrating in the same or opposite direction of the wave, as opposed to perpendicular. Therefore, a sound wave needs particles to vibrate/oscillate for it to travel. If there are no particles, it cannot travel. A vacuum is defined by the absence of matter, meaning there are no particles. Thus, sound cannot travel in a vacuum.

vacuum answer 2 Sound is a vibration of molecules, and thus cannot travel in a vacuum, where there are no molecules.

vibration
vibration and a medium for it to move through
"Cold" or "hot" are only defined when there are particles that move, so a temperature would not be defined for a perfect vacuum.

Depends on the type of wave. For example, sound makes air oscillate, but the air doesn't go anywhere Electromagnetic waves ie. microwaves, visible light, x rays, radio waves, can travel through a vacuum but if they travel through for example the air, or glass, or water they don't move the material through which they move. Mechanical waves are waves which involve the vibration (oscillation) of the particles of the material through which they move. The particles vibrate up and down, or backwards and forwards, but are not carried along with the wave. This is part of the definition of a wave, that a wave transmits (moves along) energy, not matter, the matter, if any is involved, just vibrates.
Because in space there are no particles (this is called a vacuum), however conduction and convection require particles to work eg. solids, liquids and gases have particle arrangements. So thermal radiation has to travel through space via radiation as space is a vacuum and particle-less.
a solid has a definite shape and volume.its particles are very close together ,and they do not move very fast.
