Some headache medicines are fine powders that are dissolved in water and then ingested. these medicines claim they work faster than other medicines. could this be true? why or why not?

a. false: chemicals react at the same rate in the body, as determined by body temperature.

b. false: these would actually slow the reaction because it would become less concentrated

c. true: a solid will react quicker in the liquid environment of the stomach than a gas or liquid

d. true: a fine powder dissolves quickly, this solution can more quickly be absorbed and begin working

i mean it can be true and it cant at the same time. i mean medicine doesn't always work on a person. but it is said that medicine that is in powder form is more efficient.

but i believe its D or 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.
