Four balloons of equal size are each filled with a gas under one of the following conditions: A) Hydrogen gas at room temperature, B) Hydrogen gas.. at 0 deg. C, C) Clean air at room temperature, D) Clean air at 0 deg. C. Which of these balloons will shrink the fastest? Please give an explanation with the answer.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

i think it's c. i'm not sure but i think so.

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.
