During an upcoming experiment, the procedure requires that 2.25 gallons of distilled water are added to a beaker. You quickly notice that all of the graduated cylinders in the lab are measured in milliliters. How many milliliters of water would we need to measure for our experiment?

the answer is na (sodium)

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.
