Question

1. dissolving salt in water is an example of:

When salt dissolves in water, no new chemical substances are formed. The salt can be recovered by evaporating the water. Physical changes do not change the chemical composition of a substance. Chemical changes result in the formation of new substances. Since dissolving salt in water is a reversible process and no new - substance is formed chemically, it is a physical change.
