What happens to the molecules of an object when they are heated?
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.
When things are heated up where do the molecules move?
They don't necessarily move to another place. However, the movement of the molecules INSIDE the object speeds up. (:
Why is air compressed when an object is traveling faster than the speed of sound?
The supersonic object is hitting air molecules faster than they can get out of the way, so they pile up.
What will happen as an object receives energy due to heat flow?
The molecules will move faster.
Do particles get faster as they get hot?
Particles will move faster when heated and slower when cooled.This is the reason that solid objects grow larger when heated. The particles are moving so fast they are making ti expand. Paragraph by -- Kira2k
What object vibrate?
Atoms or molecules when they are heated.
What happens to molecules of an object when the temperature rises?
when the temperature rises the molecules of an object collides even more faster and also its moves around faster.

Conductionconvection and radiation what is the specific name of these 3?
Collectively they are form s of 'Energy Transfer'. Conduction : The molecules in a hot object move/vibrate faster than in a cooler object. A hot object placed adjacent to a cool object , will make the cool objects molecules move /vibrate faster. Convection : The movement of got molecules to a cooler region. Radiation ; An electron-magnetic wave, which when it intercepts an object will make its molecules move/vibrate faster.
What happens the object when it is heated?
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.
What is the effects of heating in physical science?
When an object is heated, the molecules that make it up, and the atoms that make up the molecules, move faster. Since (in solids) they can't "go" anywhere (they're constrained by molecular bonds), they "vibrate" faster and faster. (Think of a 4 year old boy locked in a play room.) Eventually (as the temperature rises), various bonds are "broken" so solid to liquid to gas, and/or the molecules become distorted (cooked)
What happens to particles as the temperature increases?
As the temperature of a substance increases, its molecules move faster and therefore take up more space. This generally causes a substance to increase in volume when heated.
How is conduction heat transferred between hot and cold objects?
Conduction of heat means that two objects with different temperatures are touching each other. The heat of the hotter object generally transfers to the cooler object. In the hotter object, molecules are moving faster. The vibration from these molecules causes the molecules in the cooler object to vibrate faster, which translates into heat.
Why do objects expands when heated?
They expand because their molecules vibrate more rapidly resulting in more space between the molecules which makes the object expand.
When things are heated up where do the molecules move?
They don't necessarily move to another place. However, the movement of the molecules INSIDE the object speeds up. (:
Why is air compressed when an object is traveling faster than the speed of sound?
The supersonic object is hitting air molecules faster than they can get out of the way, so they pile up.
How conductivity occurs?
Conduction occurs when two object at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. Conduction is the movement of heat through a substance by the collision of molecules. At the place where the two object touch, the faster-moving molecules of the warmer object collide with the slower moving molecules of the cooler object. As they collide, the faster molecules give up some of their energy to the slower molecules. The slower molecules gain more thermal energy and collide with other molecules in the cooler object. This process continues until heat energy from the warmer object spreads throughout the cooler object.
