The elements on the periodic table are arranged in order of increasing
(1) atomic mass
(2) atomic number
(3) first ionization energy
(4) selected oxidation state

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.

how important do you think an instrument is to the musician who plays it?

the correct answer would be b) volume versus temperature, because they are also directly proportional.
