Acertain amount of gas is trapped in a nonrigid container at atmospheric pressure. if the container is cooled and the gas in the container remains at atmospheric pressure, what will happen? a. the number of moles of gas will decrease. b. the number of moles of gas will increase. c. the temperature of the gas will increase. d. the volume of the container will decrease. e. the volume of the container will increase.

D. The volume of the container will decrease.

Explanation:

PV = nRT,

where, P is the pressure of the gas.

V is the volume of the container.

n is the no. of moles of the gas.

R is the general gas constant.

T is the temperature of the gas.

Also, n is constant as there is no added external gases.

T is decreased as the container is cooled.

So, the volume will change as the container is nonrigid.

V α T.

The volume is directly proportional to the temperature,

Thus, as the container is cooled, the T will decrease, and the volume of the container will decrease.

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.
