Which of the following describes qualntive data

Option Noting the color of a solution as it is heated.

To understand this answer, let's first clarify what qualitative data is: Qualitative data is data that is descriptive, describes the attributes of something and it cannot be represented numerically. From the options listed the question, noting the color of a solution as it is heated, is the only statement that describes qualitative data. The color of a solution is an attribute of the solution that cannot be represented quantitatively-using numbers. On the other hand, the other options listed describe quantitative data, which are all measurable and can be represented numerically.

Hope this helps, have a wonderful day/night, stay safe, happy holidays, and merry christmas!

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.
