This PowerPoint presentation by Ameena Thjan.R discusses physical and chemical changes. It defines physical changes as reversible changes in a substance's physical properties, like size or shape, providing examples of melting ice and boiling water. Chemical changes are defined as usually irreversible reactions that rearrange atoms and form new substances, providing examples of rusting, cooking an egg, and milk going sour. The presentation concludes by differentiating physical and chemical changes based on whether they are reversible or irreversible and if new substances are formed.

3. CHANGES

4. TYPES OF CHANGES
 PHYSICAL CHANGES
 CHEMICAL CHANGES

5. PHYSICAL CHANGES
PHYSICAL CHANGES IS A USUALLY
REVERSIBLE CHANGE IN THE PHYSICAL
PROPERTIES OF A SUBSTANCE ,AS SIZE
OR SHAPE

6. EXAMPLES OF PHYSICAL
CHANGES
MELTING AN ICE CUBE
BOILING WATER
 MIXING SAND AND WATER
BREAKING A GLASS

7. CHEMICAL CHANGES
CHEMICAL CHANGES IS USUALLY
IRREVERSIBLE CHEMICAL REACTION
INVOLVING THE REARRANGEMENT OF THE
ATOMSOF ONE OR MORE SUBSTANCE AND A
CHANGE IN THEIR CHEMICAL PROPERTIES OR
COMPOSITION ,RESULTING IN THE
FORMATION OF AT LEAST ONE NEW
SUBSTANCE.

8. EXAMPLES OF CHEMICAL
CHANGE
RUSTING ON IRON
COOKING AN EGG
BAKING AN CAKE
ROLLING BANANAS
MILK GOING SOUR

9. DIFFERENCE BETWEEN PHYSICAL AND
CHEMICAL CHANGE
PHYSICAL CHANGE
 REVERSIBLE CHANGE
 NO NEW SUBSTANCE IS
FORMED
 TEMPORARYCHANCE
CHEMICALCHANGE
 IRREVERSIBLE CHANGE
 FORMATIONOF NEW
SUBSTANCE
 PERMANENT CHANGE
