Final answer:
Physical changes involve changes in state, shape, volume, or color of a substance without altering its chemical composition. These changes are reversible and do not affect the identity of the substance.
Step-by-step explanation:
Types of Physical Changes include:
- Change in state of matter (solid, liquid, gas)
- Change in shape or form
- Change in volume or density
- Change in color (without a chemical reaction)
Physical changes affect the form of a substance but do not change its chemical identity. These changes are generally reversible and do not involve the making or breaking of chemical bonds. Examples of physical changes include melting ice, dissolving sugar in water, and shredding paper.
