Predict the changes in the number of particles based the diagram.
a) pressure is indirectly related to moles.
b) volume is proportionally related to moles.
c) moles remains constant as pressure changes.
d) temperature is directly related to the moles.

The changes in the number of particles based on the diagram is that Volume is proportionally related to moles. The answer is letter B. The rest of the choices do not answer the question above.

Pressure is indirectly related to volume.

As the volume increases at a constant temperature, the pressure decreases.

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.
