If your an FLVS student, then it will not show up. Lol. Sorry.

This is a physical change.
Physical
whats the answer
No. Only the weaker physical bonds that hold covalent molecules in a liquid state are broken by boiling or other vaporization.
Chemical change or chemical reaction describes how a substance can form a new substance.
Yes! Wanna cookie?
This physical phenomenon (a change of phase) is called melting; during melting the chemical nature of molecules is not changed but the bonds between molecules are weakened.
no. melting is a physical change and does not involve breaking of covalent bonds
This is a physical change.
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
Its because of the bonds between molecules or atoms breakng or forming. For instance when a solid is formed bonds are made between the molecules of the substance creating a rigid structure, if these bonds were broken then the substance would be able to flow like a liquid.
After a chemical reaction, some of the bonds have been broken, and some new bonds have been formed. So, that's how a substance is changed after the reaction.
Covalent bonds are the easiest to break, since they are the easiest to make. But no substance is made when bonds break.
