Question

why is ice melting a physical change?

ice and water are the same molecule.
ice and water are different molecules.
the atoms change into different atoms.

Explanation:

Define physical change

A physical change alters the form or state of a substance without changing its chemical identity.

Analyze ice melting

Melting is a transition from solid to liquid. Both ice and liquid water consist of \(H_2O\) molecules.

Evaluate the options

The chemical composition remains identical, meaning ice and water are the same molecule.

Answer:

• Ice and water are the same molecule. (Correct answer)
• Ice and water are different molecules.
• The atoms change into different atoms.
