For many purposes we can treat ammonia (NH) as an ideal gas at temperatures above its boiling point of – 33. °C. Suppose the temperature of a sample of ammonia gas is raised from 85.0 °C to 121.0 °C, and at the same time the pressure is
increased by 15.0%.
increase
Х
Does the volume of the sample increase, decrease, or stay the same?
decrease
O stays the same
If you said the volume increases or decreases, calculate the percentage change in 0%
the volume. Round your answer to the nearest percent.

a. hope i'm right

explanation:

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.
