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.

Does molecular motion stop when diffusion stops?
No molecular motion only ceases when the temperature is at absolute zero. The molecules have retained their kinetic energy although they are at equillibrium.
What temperature scale places zero at the point where all atomic and molecular motion ceases?
On the Kelvin scale, zero is the temperature at which there is no atomic or molecular motion.
How does adding heat affect molecular motion?
Me no English
How would you describe the molecular motion of a solid?
Lethargic
What state of matter has the greatest molecular motion?
Gas
Which state of matter has the least molecular motion?
The solid state has the least molecular motion.
The direct transfer of molecular motion through solids?
The direct transfer of molecular motion through solids is called conduction
Describe the molecular distance and motion in the three states of matter?
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.
When a substace is heated how does the molecular motion change?
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.
What is the Erratic motion of microscopic particles caused by random molecular motion?
That is called Brownian motion.
What does the word diffusion mean?
it is the transport of molecules from a region of higher concentration to one of lower concentration by random molecular motion.
Does molecular motion stop when diffusion stops?
No molecular motion only ceases when the temperature is at absolute zero. The molecules have retained their kinetic energy although they are at equillibrium.
What temperature scale places zero at the point where all atomic and molecular motion ceases?
On the Kelvin scale, zero is the temperature at which there is no atomic or molecular motion.
What is the exact molecular motion of liquid?
It is not known and, thanks to Brownian motion, it cannot be known.
What is the molecular motion of a gas?
They move around freely!!
What is the molecular motion of sol id?
It vibrates slightly.
Which phase has the second greatest molecular motion?
Liquids
