Presentation transcript:

 How does double glazing the windows keep the house warm? What mode(s) of heat transfer is blocked by double glazing?

 How can a home be made warm in winter? Identify the mode of heat transfer each method uses to keep the house warm.

 On which side will your hand feel hotter: above (but not touching) the flame or below it? Why?

 Explain why the igloo can keep the Eskimo warm even if it is made of ice.

 A newspaper wrapping keep hot things hot and cold things cold. Why? What other wrappings can be used that works like a newspaper?

 What is the advantage(s) of placing the electric heater near the bottom of a bucket of water compared to putting it near the surface? What is the disadvantage(s)?

 Why do we have sea breeze in the morning and land breeze at night?
