When you heat up an object the particles in the object move?
faster
What is an effect of heat on the temperature of an object?
it makes the particles move faster so it expands.
What do particles do during expansion and contraction?
If the object is heated it will expand because the particles gain energy from the heat and move about more vigorously causing them to bump into each other and move further and further apart. When the substance is cooled (gets cold) the particles slow down and move closer and closer together causing the object to contract.
Do all things radiate?
Yes, all objects radiate some heat BUT the hotter the object, the more heat it radiates!! radiation its self is not hot but when it is absorbed by an object its particles in the object move more rapidly thus heating it
Do particles in a hot object move slower than those in a colder object?
No,it is actually the other way around.Particles in a hot object move faster than particles do in a colder object.

Heat makes the particles in matter move how?
Heat is the average kinetic energy of something. When you increase the heat, you make the particles in the substance move faster. It would be more correct to say that particles moving in a liquid (or any substance rather) cause heat. So increasing heat causes particles in a liquid to move faster. Hope that helps.
Do particles in sold ice move slower than particles in liquid water?
Yes. The colder the substance become, the slower the particles move. Actually in pure ice the particles do not move at all.
Why would particles speed increase if heat was added?
Any object consists of particles. In a solid they are close together and do not move much. In a liquid the particles can move more freely past each other as they have more heat energy. In a gas the heat energy is largest and the particles move fastest. By heating any object we add heat energy to it. This speeds up the particle movement as the energy increases. It also expands the bonds between the particles and, if this goes far enough, the object changes state. (Ice melts when heated from solid to liquid)
What is energy that is due to random motion of the particles in a material is?
most likely thermal as the more particles move the more heat the object produces.
Explain how the motion of particles in an object changes when its temperature increases?
When temperature increases the particles of an object gain more heat energy, therefore move faster colliding with each other more.
How do particles of a solid move?
If the object is completely solid the particles don't move
What do particles do during expansion and contraction?
If the object is heated it will expand because the particles gain energy from the heat and move about more vigorously causing them to bump into each other and move further and further apart. When the substance is cooled (gets cold) the particles slow down and move closer and closer together causing the object to contract.
When heat is absorbed by an object the speed of the particles in an object is?
increased.
