At the molecular level iodine gas contains I2 molecules, which if you could see them ( they are too small to be seen using light) and you were able to see the electron density then they would appear as small dumbells. When iodine sublimes the colour of the "gas" is violet this due to the aborption of visible light by the I2 molecule.
they look like small circles which float around
magenta vapout
Violet - blue I2 molecules
they are all over the place. e.g. scattered.
In a gas, particles are in constant motion and spread out to fill the space available. They have weak interactions with each other and the container walls, leading to high kinetic energy and random motion. The particles are very small compared to the distance between them.
You can not see Gas!!!!!Though there are some gases with colour to see: this one is violet - blue I2
Liquid's particles are much more organized than a gas. Gas particles will move around with very high speeds resulting in pressure.
Salt look like little cristals particles.
Because the particles are further apart (look up the particle model) :)
Because hot gas particles have greater kinetic energy than cold gas particles
Aerosol particles are solid or liquid particles suspended in a gas. These particles can be natural (like dust, sea salt, or pollen) or man-made (such as smoke or smog) and can have various environmental and health impacts when inhaled.
To create a working model demonstrating movements of particles in solid, liquid, and gas, you can use different sized balls for particles to represent the three states of matter. For a solid, pack the balls tightly together and show minimal movement. For a liquid, spread the balls out slightly and allow them to slide past each other. For a gas, scatter the balls far apart and show random movement in all directions. By visually comparing the movements of these particle models, you can effectively demonstrate the behavior of particles in different states of matter.
