Which of the following statements is most accurate?
a. when liquid water is heated, the molecules move faster.
b. when liquid water is heated, the molecules collide more often.
c. when liquid water is heated, collisions between molecules are more violent.
d. all of the above.

bcde is the incorrect answer it is a

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.
