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.
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. (:
When an object is heated and its temperature increases, the atoms within the object move more rapidly, causing them to push farther apart. This expansion results in an increase in the volume of the object.
When molecules are heated, their kinetic energy increases, causing them to vibrate and move more rapidly. This can lead to a change in state from solid to liquid or liquid to gas, depending on the amount of heat applied. In some cases, heating molecules can also cause chemical reactions to occur, leading to the formation of new compounds.
When air is heated, gas molecules gain kinetic energy and move faster. This increased movement causes the gas molecules to spread out and occupy more space, leading to an expansion of the air. Additionally, the pressure of the gas increases as the faster-moving molecules collide more frequently with the container walls.
Atoms or molecules when they are heated.
new molecules starts to form
As an object is heated, its molecules gain more kinetic energy, causing them to move faster. This increase in molecular motion results in higher average speeds of the molecules, which is why the object feels hotter to touch.
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.
It expands.
they get exited and move faster than cold molecules
The liquid molecules are transformed in gas molecules.
The liquid molecules are transformed in gas molecules.
they get farther apart.
what happens to water molecules when they are heated
The magnitude of the vibration of its molecules gets increased.
the hot-air molecules bang on each other harder.
