so that A student and a half-filled a syring with water. She then carefully drew blue ink into the springe up some lit formed a seperate layer below the water She then left the springe in a clamp for twenty hours. al Use the kinetic partical theory to explain these observations

c. electrical charges of ionic bonds.

the objects have the same charge is correct.

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.
