Question

When water is frozen, it forms ice that has different properties. Why then do we say that freezing is a physical change?

Answer 1

• Physical change: a temporary change, in which no new substance is formed and the chemical composition of the original substance remains the same, even though some of its physical properties like color, state, shape, size, etc. may change.
• For example, melting of iron and wax, etc.
• When water is frozen, the ice thus form has the same chemical properties as that of water only there is a change in the state of water from liquid to solid. That is why freezing of water is a physical change.
