Thermal energy can be transformed to do work .
true
false

FALSE!!! Thermal energy can be transformed to heat.

Explanation:

False

Thermal energy is unique because it cannot be converted to other forms of energy. Only a difference in the density of thermal/heat energy (temperature) can be used

Explanation:

Have a great day!

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.
