In what way does convection depend on the density of a substance? Group of answer choices Warmer fluids sink below cooler fluids because warmer fluids are denser. Warmer fluids rise above cooler fluids because warmer fluids are denser. Cooler fluids rise above warmer fluids because cooler fluids are denser. Cooler fluids sink below warmer fluids because cooler fluids are denser. Brainliest to first person who anwsers this correctly :)

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

explanation:

diaria maybe go see a doctor about that

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.
