Answer: Physical
Explanation
- A change in physical appearance or state of a substance, such as a change in shape, size, color, or phase (solid, liquid, gas), is called a Physical Change.
The are examples of Physical Changes:
- Melting (ice cream, wax, chocolate, ice and change from solid to liquid)
- Phase changes (boiling, freezing, condensation)
- Crushing (chalk)
- Tearing (paper)
- Crumpling (aluminium foil)
- Stretching (rubber band)
- Mixing (sugar in water)
- Dissolving (sugar, salt in water)
- Moulding (clay, metals)
- Slicing (fruit)
- Forming of frost (from water vapors)
- Transition to a gas (change from liquid to gas)
- Change of durability (change in texture or strength)
- Changes to crystal form (change in crystal structure)
