When molecules of something are heated, they absorb the thermal energy and start to vibrate. When enough thermal energy is applied, then the chemical bonds break, and the atoms and molecules are now moving freely. If metal is heated for long enough at the right temperatures, then the molecules will disconnect, move freely, turning the metal into a liquid. But if its a type of fuel like wood or coal, then molecules rise to the air and immediately react to the oxygen causing an instant combustin reaction. Im 13 and hope this helped.
They will move faster (increase in speed).
when molocules are heated up they start to move faster and faster and the gas spreads around the room
The speed of the particles increase also.
When molecules are heated they become more active. When they are cooled, the slow down.
The molecules in side move or spread apart
They don't necessarily move to another place. However, the movement of the molecules INSIDE the object speeds up. (:
The gas molecules go upward. Sorry I dont have any more information but this was all I ould find out
The gas molecules receive kinetic energy and start to vibrate
The molecules in an object begin to move because of the heat. The moving of the molecules cause the space between them to expand. That is how blacksmiths are able to change the shape of metals.
Atoms or molecules when they are heated.
they pop
new molecules starts to form
Thermal decomposition
It expands.
The liquid molecules are transformed in gas molecules.
they get exited and move faster than cold molecules

It changes the vibrations of the molecules.
