Adrop of water weighing 0.48 g is vaporized at 100 ? c and condenses on the surface of a 55-g block of aluminum that is initially at 25 ? c. if the heat released during condensation goes only toward heating the metal, what is the final temperature in celsius of the metal block? (the specific heat capacity of aluminum is 0.903 j/g ? c.

What is the number of moles of chemical units represented by 9.03x10^24? and how do i show work? (dumb it down )

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks. energy was destroyed inside the blocks. energy was absorbed into the blocks from outside the system. energy was transferred from the warmer block to the cooler block.
