What will happen energetically to a cup of boiling hot water that is added to a cup containing a cold piece of metal?
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
Does aluminum shrink in water?
Aluminium is a metal, and solid well beyond the point where water has evaporated. Aluminium is also extremely unreactive with water when simply placed in it. There is thus no reason why the metal would shrink or otherwise change its shape (apart from the obvious one of placing hot metal in cool water, or quenching, but this is a result of thermal effects, not just because you put aluminum in water).
