Your roommate has learned that burning approximately 3,500 food calories (the food calorie is a quantity equal to a kilocalorie, kcal) results in a weight loss of 1 lbm, and he gets the bright idea of losing weight rapidly by eating ice.

his theory is that the energy expended by the body in melting the ice and raising the resulting liquid water to body temperature will do the trick.

you burst the poor boyâs bubble by telling him the amount of ice he would have to consume.

how much ice would be required per pound of weight lost?

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

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.
