1. In physical change, particles do not change but in chemical change particles change and thus, creating a new substance
2. Physical Change:
(a) Water Cycle (Evaporation, Condensation, Previpitation)
(b) Cutting of Paper
(c) Molding clay
Chemical Change:
(a) Burning of Paper
(b) Rusting of iron
(c) Dissolving of limestone due to carbonation
3. The difference between chemical and physical change is that in physical change, no new material is formed. Change in shape, size, color, volume, densuty and phase (solid, liquid, gas) is considered physical change. On the other hand, chemical change is a change that occurs when there is a new substance form and the matter cannot be reversed back to its original form.
