When a steaming-hot aluminum soda can is quickly inverted into a pan of water, the can is dramatically crushed due to a rapid decrease in internal pressure caused by
 
  A) contact with the cooler water.
  B) sudden slowing of internal air and steam molecules.
  C) condensation of steam inside.
  D) reduced thermal energy.
  E) rapid conduction of heat to the relatively cool water.

Answer to Question 1

Answer: C

Answer to Question 2

Muchas Gracias :)

Answer to Question 3

Answer: The 100-W bulb has less resistance and a thicker lamp filament, for it draws more current. This is consistent with the power relationship: P = IV. More current I for the same voltage V means less resistance. (It is important to note that both watts and volts are printed on a light bulb. A bulb that is labeled 100 W-120V is 100 W only if there is 120 V across it. If there is only 110 V across it, then the power output is only 84 W)
