Question

Which of these is an example of a physical change? Question options: melting a substance breaking chemical bonds forming chemical bonds nuclear decay

Answer 1

Examples of physical changes are boiling, melting, freezing, and shredding.

So anything that is melting; like you said, melting a substance.

A chemical reaction occurs when chemical bonds are broken and formed and atoms are exchanged to produce chemically different species. Both of these processes are chemical reactions.

For Nuclear Decay:

Radioactive decay is a nuclear—rather than chemical—reaction because it involves only the nuclei of atoms. In a nuclear reaction, one element may change into another.
