3. HEAT transfer What happens if you put water on a hot stove? The water gets hot because heat from the burning stove is transferred to it.

4. Thermal Energy

5. Thermal Energy Refers to the energy possessed by an object due to the movement of particles within the object HEAT is an energy that is transferred from one object to another due to the difference in their temperature.

6. Temperature refers to the relative hotness or coldness of an object it can be measured using a thermometer

7. THREE METHODS OF HEAT TRANSFER CONDUCTION CONVECTION RADIATION

8. THREE METHODS OF HEAT TRANSFER CONDUCTION takes place between objects that are in contact with each other. What do you think is the reason why cooking pans are made of metals? EXAMPLES OF A GOOD CONDUCTOR OF HEAT: Pans is a good conductor of heat. Silver Copper Steel Aluminom

9. THREE METHODS OF HEAT TRANSFER CONVECTION is the method of heat transfer to the circulation of liquid and gas
