Science How do the properties of synthetic materials compare to the properties of petroleum?
How do the properties of the synthetic material contribute to its function?

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.

so d

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.
