bot can you help me?
Yes, each of these processes involves a physical or chemical change:
1. Ice melting is a physical change because it involves a change in the state of matter from solid to liquid without changing the molecular structure of water molecules.
2. Eggs cooking is a chemical change because when eggs are heated, the protein molecules denature and coagulate, causing a irreversible change in their chemical composition.
3. Salt dissolving is a physical change because it involves breaking apart ionic compounds into their constituent ions without changing their chemical identity.
4. Wood burning is a chemical change because it involves a chemical reaction between the wood and oxygen in the air, resulting in the release of heat, light, and the formation of new chemical substances like carbon dioxide and water vapor.
5. Fireworks exploding is also a chemical change because it involves a rapid combustion reaction within the fireworks that produces heat, gas, and light, resulting in the creation of new chemical compounds.
