Answer 1

Hello buddy.....
Here is your answer......

2. Th pizza box is wrapped up in a glass sheet to produce green house effect and the heat is not let out.

3. In winter the black shirt makes him comfortable because black absorbs more heat.
In summer white shirt makes him feel comfortable beacuse white colour absorbs less heat.

4. It is difficult to hold a pan if it's handle is hot. Since wood and plastic are bad conductors of heat , the handles are made with them and the pan needs to be a good conductor of heat so that it conducts more heat and spreads the heat uniformly.

6. Thermos flask prevents transfer of heat through any mode such as conduction/convection/induction.

7.The molecules of air are farther thereby a lot of heat is wasted in transfer.

12. Since black absorbs more heat the inside of a solar cooker is painted black.




Hope this helps.....
