Suppose that 232 mL of argon is collected over water at 25 ◦C and 732 torr. Compute the volume of the dry argon at STP. The water partial pressure at 25 ◦C is 23.8 torr. Answer in units of mL.

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.
