The molar heat capacity of ethane is represented in the temperature range 298 k to 400 k by the empirical expression coin uk moll 14.73 + (0.1272 mt in k). the corresponding expressions for c and hziai are given in the back of the atkins textbook. calculate the standard enthalpy of formation of ethane at 373k from its value at 298 k, in kj moll

the answer is a. co2, this would be colder than the : )

explanation:

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.
