TRANSFER OF HEAT. science lesson for grade 5 learnerspptx

Powerpoint presentation about Science Lesson, Understanding transfer of heat.

1. Transfer of Heat Teacher: Chries Bell Cleofe

2. How does heat travel? Just as light travels from one medium to another, heat also travels from one object or place to another. Heat travels from a region of higher temperature to a region of lower temperature through conduction, convection, and radiation.

3. Transfer of Heat Convection

4. Let’s Watch!

5. Understand Conduction More! When an object is heated up, its particles collide with one another. So, heat is transferred from the hotter region to the cooler region through these collisions of particles.   Conduction can also occur between objects. Heat is transferred when particles of both objects are touching each other.  

6. Conduction Heat can transfer from one part to another within an object or between objects. This type of heat transfer is called conduction.

7. The transfer of heat from one region to another by the movement of fluids is known as convection. When a fluid is heated up, it expands. This means that its volume increases and its density decreases. The hotter, less dense fluid then rises and floats, while the cooler, denser fluid flows to take its place. Convection

8. Radiation Radiation is the release of heat from the surface of most bodies that is transferred directly from one region to another.   Heat is directly transferred without having to travel through any substance. This means that heat can be transferred even if there is no air.

9. Let’s Try It Out! I dentify whether the picture shows Conduction, Convection or Radiation.
