HELPPP MOvens cook food by heating up coils which heats up the air inside the oven. Imagine placing cookie dough into an oven that
only has coils in the middle of the oven on the bottom. Where
would you want to place the cookie dough so that it cooks the
slowest? Explain using your knowledge of convection.

answerleaving cheese out to get moldy;

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
