gases have losely packed molecules which hit each other and produce kinetic energy which helps them to spread.
In a solid, the particles are tightly packed and do not move around much, as opposed to a liquid or gas, in which the particles are more spread out.
As gas particles bounce around and collide, they spread to fill the available space of their container. This is because gas particles have high kinetic energy and move freely in all directions due to their random motion.
When particles are spread out and moving rapidly, the temperature increases. This is because the kinetic energy of the particles is higher, causing more collisions and leading to an overall increase in thermal energy and temperature.
Because diffusion involves the random movement of particles. In a solid, particles cannot move to an area of low concentration as the intermolecular forces are too great. So the particles stay tightly packed in a solid.
In the gas phase, the particles spread out to completely fill their container.
Because what you smell is actually tiny particles of whatever it is being spread around in the air.
Gas particles have high kinetic energy, allowing them to move and spread out quickly. This property is known as diffusion, where gas molecules disperse from areas of higher concentration to lower concentration until they are evenly distributed. The rapid and random movement of gas particles enables them to cover larger distances in a shorter amount of time compared to liquids or solids.
In a homogeneous mixture particles are spread evenly.
Technically the particles are moving randomly in all directions, its just that after some time this random movement causes them to spread out, giving the appearance that they are moving directly to the place of lower concentration. Do you need more detail? Hope this helps!
The region of spread out particles in a wave is called the trough. This is where the particles are at their lowest point of displacement from their equilibrium position.
Rarefaction is the part of a longitudinal wave where the particles are spread apart.
A longitudinal wave has areas where particles are spread out. In this type of wave, particles move parallel to the direction of the wave propagation, causing areas of compression (particles close together) and rarefaction (particles spread out). Sound waves are an example of longitudinal waves.
