No, melting is never chemical! Neither is boiling, freezing, etc. Those are changes of 'the STATE of matter' and purely physical.
Endothermic reactions are those in which energy is absorbed during the reaction. Exothermic reactions are those in which heat is evolved during the reactions.When ice melts its absorbs energy in the form of heat so why it melts,
The chemical structure is unchanged.
When ice melts, the chemical composition remains the same. Ice is just the solid state of water, so when it melts, it turns into liquid water. The molecules in ice rearrange themselves into a more disordered state to become liquid water, but the chemical makeup of the water molecules themselves does not change.
When ice melts, it undergoes a physical change, not a chemical change. The molecules in the ice are still the same water molecules, but they are transitioning from a solid state to a liquid state.
No. It is water before it melts and it is water after it melts, so melting water is a physical thing, not chemical.
chemical change
Melting is a physical process; reaction with sodium is a chemical process.
Physical Change
They're both physical changes. Phase changes are always physical changes. Chemical changes only involve chemical reactions - a change in the identity of the substance. That's why phase changes are physical changes. Ice cream remains ice cream when it melts.
Melting is not a chemical change because the chemical formula of water remain unchanged.
Physical because none of its chemical property's are not changed. Its still ice, just melted
