A chemical reaction involves changing the materials that your dealing with into new materials, thus new appearances and solutions form from the combination of the 2 materials.
ex. Sodium (Na) + Chlorine (Cl) = Sodium Chloride (NaCl)
A phase change is simply a changing of an elements state.
ex. water ~ ice --> water --> vapor
hope this helps.

Try looking in your text book
A physical change is a change that does not change the chemical makeup of the substance. This can be crushing, tearing, or a phase change for example. A chemical change changes the chemical makeup of the substance. Some examples of this are rusting, combustion, or digestion.
Physical Change. =KDML= ;)
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
You can't.
"Chemical reaction rates vary with the conditions of the change but nuclear rates do not."
A chemical change results in a change in chemical composition, while a physical change does not.
physical change are reversable
The physical change will keep the atoms the same not moving but the chemical change will make it move around with energy.

No. It is a nuclear change.
This does not happen, they are quite differenwell sometime chemical change into nuclear by going to thermal energy
It is a nuclear change because there is a change in the nuclear structure of Uranium.
physical change is when you physically change (your finger grows EG.). chemical is when a chemical in your body is affected (a drug that makes you produce more adrenaline EG.).
It is a nuclear change not a chemical one. The energy for the yield originates from the nuclei of the atoms and the electrons (where chemical energy resides) are uninvolved in the process.
Physical changes are melting and boiling in this case; fire is a combustion, a chemical change.
