the denseness of the molecules change(compact=solid, really far=gas, in the middle=liquid)
The reactants are transformed in products, substances with another type of molecules and properties.
the state of matter changes from liquid to gas, so the molecules spread out.
The reactants are transformed in products of the chemical reaction - if you understand molecules by particles of matter.
Well it'll slows down and maybe change state of matter
Matter exists as solids, liquids and gases. When a substance change phases, the molecules will change size coupled with the increase or decrease of heat energy.
Nothing happens to the atoms within the molecules,but the molecules move around slower.
This change in the state of matter (liquid to solid) is called freezing.This change in the state of matter (solid to liquid) is called melting.They are physical change, the chemical nature of the molecules is not changed.
It changes the vibrations of the molecules.
One thing that happens is that the molecules in the matter lose energy and momentum and slow down, therefore the matter becomes more compact.
When water freezes, the matter condenses and the molecules move slower.
The chemical change of matter is what happens when you have something changed chemically
A chemical change involve a change of composition.
nothing happens or in other words, nothing happens to the molecules. the only change, is in the way they move closer and furthuer from each other. pretty much it make change in look slightly but it is still in the same substance. it may change its state of matter
If by matter you mean molecules / atoms then no. Physical change is when the look / shape of something is changed but not its chemical structure, chemical change is when the molecules that make up the object n question are changed.
the atoms use the energy to move the molecules
A change of matter from one form to another without a change in chemical properties is a physical change.
Technically speaking, the switch of state of matter is the rearrangement of its molecules. Solids have tightly packed molecules that are close together. Liquids are relatively farther apart and take the shape of its container. Gases' molecules are the farthest expanding and they keep separating until they expand completely.
You change one state of matter to another by heating the matter or cooling it [aka] adding energy or removing the energy
it will change to liquid
Thys is a physical change: melting, boiling, sublimation, griding, etc.
heat, heat can change the state of matter therefore speeding up molecules.
What happens when an object gains thermal energy?
A change of matter from one form to another without a change in chemical properties is a physical change.
in a physical change, matter does NOT change its idenity, on shape, size, ect. that include being a maleabilty
False.Atoms themselves only change during nuclear decay, fusion or fission. Outer electrons can be shared, donated or received during bonding but the atom doesn't change in and of itself.When matter changes state the bonds themselves are not affected. All that happens in a change of state is that molecules gain more kinetic energy. The bonds within the molecules are not altered.
