A chemist places a 100 g cube of each of the metals listed in the table on a separate hot plate. All of the
hot plates are identical. Each hot plate is set on medium heat, and all of the cubes have the same initial
temperature. Based on the specific heat values in the table, rank the metals in terms of how quickly they
will reach the target temperature of 80°C. Use "1" to indicate the fastest and "5" to indicate the slowest.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

the correct answer would be d. hope this !

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

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.
