Which term best describes liquid behavior under pressure? incompressible compressed immiscible surfactant

Option a incompressible

Explanation:

Liquids have definite volume, but indefinite shape.

Liquids take the shape of the container . When a liquid is inside a container, it will take its shape. Unlike gases, a liquid cannot change its volume to spread out and completely fill a container.  Hence a liquid cannot be compressed.

Immiscible is not right because this applies only when two liquids are there

Surfectants are compounds that reduce the surface tension between two liquids or a liquid or a gas, etc.

Hence here appropriate choice is

a) incompressible

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.
