The heat capacity of the several metals is shown below. Metal Heat capacity in J/(kg.)
Au 130
Pt 134
Ag 234
Cu 385
Which metal will show the greatest increase in temperature if 120 J of heat is supplied to a 50 g sample of each metal at
the same initial temperature?
Au
Pt
Ag
Cu

i need mutiple choices

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.
