A block of aluminum weighting 140.0 g is cooled from 98.4oC to 62.2oC with the release of 1080 J of heat. From this data, calculate the specific heat of aluminum. J/g*oC (Your answer should have 3 numbers after the decimal)

i'm pretty sure its b i might be wrong though!

the answer is 0.42 is that is an option. this question provides no info

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.
