At higher elevations, the boiling point of water decreases, due to the decrease in atmospheric pressure. As a result, what
could be said about hard boiling an egg?
a. At higher elevations, it would take less time to hard boil an egg, because there is less atmospheric
pressure
b. At higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point,
so the egg is boiling in water at a lower temperature.
C. At higher elevations, it would take less time to hard boil an egg, because there is a lower boiling
point. Therefore it would take less time to achieve the boiling point.
d. At higher elevations, it would take longer to hard boil an egg, because it would take longer to
achieve the boiling point.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )

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.
