A glass of water is at room temperature in an isolated system. What will happen if one ice cube is added to the system? A
Heat will be removed from the system, causing the liquid water to lose some molecular motion but retain its state.

B
Heat will be removed from the system, causing the liquid water to lose some molecular motion and change state.

C
Heat will be added to the system, causing the liquid water to gain some molecular motion but retain its state.

D
Heat will be added to the system, causing the liquid water to gain some molecular motion and change state.

have a great day because if you dont you and i will be sad

the correct answer would be d. hope this !

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.
