Dissolving is when a substance has mixed into a solvent.
Diffusion- the mixing of molecules of one fluid through another by random molecular motion.
Lethargic
When the temperature increases during a chemical or physical change the molecular movement increases. This means the molecular movement is faster. If the temperature decreases the molecular movement decreases. This means the molecular movement is slower.
No molecular motion only ceases when the temperature is at absolute zero. The molecules have retained their kinetic energy although they are at equillibrium.
On the Kelvin scale, zero is the temperature at which there is no atomic or molecular motion.
The two factors that describe motion are thing. :)
Lethargic
Molecular distance is the furthest and the motion is the fastest in gases. Molecular distance is closer and have much slower motion in liquids. Molecular distance is closest and the molecules move very very slowly (kind of just shake) in solids.
Brownian motion
The solid state has the least molecular motion.
The direct transfer of molecular motion through solids is called conduction
Diffusion is the movement of molecules from a region of higher concentration to one of lower concentration by random molecular motion.
During diffusion molecules move from a region of higher concentration to one of lower concentration by random molecular motion.
The average speed of the random molecular motion increases. The corresponding increase in molecular kinetic energy accounts for what happened to all of that heat energy.
That is called Brownian motion.
When the temperature increases during a chemical or physical change the molecular movement increases. This means the molecular movement is faster. If the temperature decreases the molecular movement decreases. This means the molecular movement is slower.
The Kinetic Molecular theory is used to describe the behavior of gas. It gives the relationship between pressure, temperature and kinetic energy.
On the Kelvin scale, zero is the temperature at which there is no atomic or molecular motion.
