What trends did you notice about the temperature of the soil and the air temperature over time? question 1 options: when air temperature increased, soil temperature increased. when air temperature decreased, soil temperature increased. when air temperature decreased, soil temperature decreased. both a and c

it would be B when air temperature decreased, soil temperature increased.

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.
