Aliquid is in a closed container and has a constant vapor pressure. what is the relationship between the rate of evaporation of the liquid and the rate of condensation of the vapor in the container?

Explanation:

When liquid in a container has a constant vapor pressure , it means that the vapor content of the liquid is constant. This further means that the rate of evaporation of liquid is equal to the rate of condensation.

Therefore, the relation between evaporation and consdensation,

rate of evaporation = rate of condensation.

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.
