Liquids. There are more collisions, but the majority are at lower energies.
They move freely in all directions (except collisions), no forces between each other
Diffusion results from collisions between moving molecules. If the molecules are moving faster, they will collide more frequently. That will make them spread out, or diffuse, more quickly.
Yes, as water is heated, the molecules continue to speed up until they are moving so fast that they fly off which is what we call steam when you are boiling water.
The molecules in a solid vibrate in place. The molecules of a liquid are moving about.
Water molecules are linked by hydrogen bonds.
Attractions between molecules may affect the viscosity of a liquid because if the molecules aren't attracted close enough together, the viscosity will be much lower (the liquid will have a watery appearance). If the molecules are closer together, the liquid will have a higher viscosity
No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.
In liquid, there is less space to move so collisions are more frequent between the molecules causing a slower diffusion rate. The opposite happens in gases. There is more space in gases. As a result, there are less collisions between the molecules causing a faster diffusion rate. Other factors that may have an affect on diffusion rates are temperature, mass of the molecule, volume/surface area, and medium used.
molecules of a solid break up get's into the space that is in between the liquid molecules
the frequency and energy of the collisions between the solute and solvent particles
The molecules in a liquid are densely packed than in a gas. The shorter distance between the molecules allows the energy to transfer more efficiently between molecules, therefore allowing more heat to pass between them.
Due to weak secondary forces between molecules...
