Define saturated and unsaturated fats​

-A saturated fat is a type of fat in which the fatty acid chains have all or predominantly single bonds. 

-An unsaturated fat is a type of fat containing a high proportion of fatty acid molecules with at least one double bond.

Unsaturated fats are healthier than saturated fats.

Explanation

Unsaturated fat:

Unsaturated fat is a kind of fat. It is different from saturated fat in that it is liquid at room temperature while saturated fat is more solid. Its molecules contains double bonds whose carbon atoms that are not fully saturated with hydrogen.

saturated fats:

From a chemical standpoint, saturated fats are simply fat molecules that have no double bonds between carbon molecules because they are saturated with hydrogen molecules. Saturated fats are typically solid at room temperature.

hope it helps ^^.

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.
