Answer:
Ice melting is a physical change. Physical changes are changes which affect the form of a chemical substance, but not its chemical composition. Certain factors, such as, temperature, contribute to the melting of ice, but it will be classified as a physical change, because the number of molecules present in the water does not change.

Answer:
Spoons are usually made out of steel
Photosynthesis is the ability for a plant to turn light into energy, thus feeding it
The branched structure isomer will require less energy to melt than the straight chain isomer
explanation
Branched structure isomer has weak intermolecular forces of attraction as compared to straight chain isomers. In addition the branched isomer has a low boiling point as compared to straight chain isomers. Since boiling require the of the intermolecular forces tend to have lower boiling point than straight chain
