8. Adding salt to ice melts the ice at a lower temperature than the normal melting point of
ice. Explain what changes occur in the process
that causes ice to change to water, with and
without the presence of salt.

Explanation:

if you have ice and you add salt it will melt!

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.
