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.
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.
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. (:
Does the temperature of liquid or solid affects the speed of sound traveling through them?
yes, if the state of matter is heated or cooled, the distance between the molecules in that object are either spread out or pulled together; therefore, the sound waves will travel quicker through heated material, and slower through cooled material.
How temperature affects particle movement?
Temperature IS the average speed of movement of the particles molecules that make up an object. The more heat you add to an object, the faster the molecules move vibrate. There are devices thermometers that indirectly measure this speed, and thus report the temperature.
What idea explains that molecules of an object military be faster as the object is heated?
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.
When an object is heated what is it's decrease in volume called?
The decrease in volume of an object when it is heated is called thermal expansion. This occurs because the molecules within the object gain energy and move faster, causing them to spread out and take up more space.
What object vibrate?
Atoms or molecules when they are heated.
How does temperature affect objects?
Temperature affects objects by expanding or contracting their molecules. When an object is heated, the molecules move faster and spread out, causing the object to expand. Conversely, when an object is cooled, the molecules slow down and move closer together, leading to contraction.
How is air heated by conduction?
Air is heated by conduction when it comes into direct contact with a warmer surface, such as the ground or a heated object. The heat energy is transferred from the surface to the air molecules through direct contact, causing the air molecules to gain kinetic energy and move faster, increasing the air temperature.
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.
When most objects are heated?

Why does the temperature of an object rises when it is heated?
Temperature is the measure of heat in a body, as measured by the motion of its molecules. As you are providing heat energy to the body, the molecules of the body gain kinetic energy (due to the principle of conservation of heat). Hence the temperature increases unless it is transferred or radiated elsewhere.
What happens to the molecules of an object when they are heated?

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.
When an object is heated why does the volume increase?
Matter is composed of molecules. These molecules move around. The movement stops only when a body of matter reaches absolute zero (about -253 degrees Celsius). The higher the temperature, the more movement. With movement increase, the distance between molecules increases, so the volume gets bigger.
Can heat energy change to sound energy?
Yes, heat energy can change into sound energy. When an object is heated, its molecules vibrate faster, creating thermal energy. If the object is a solid, these vibrations can produce sound waves that we hear as sound energy.
