Another chemistry problem?

500 ML beaker full of water and 1.0 L beaker Full of both. Brass cube, 2.0 cm at the edge where the water from the smooth 1.0 L beaker with a rectangular block of cork 5.0cm X 4.0cm 500 ML beaker of water X 2.0 cm. The density of brass, 8.40 g / cm ^ 3, and the cork is 0.22 g / cm ^ 3's. The spacecraft Large volumes of water will overflow? Explains. The answer is the cork, I do not understand why. A loaf of Brass 67g ... To get and therefore, will sink to 67 ML of water displacing it? 8.8g net mass of the cork came out in, and floats Therefore, the right only Displacing the water with 8.8 ML? So, while I do not understand how the floating Captain 8.8g 67g blocks of cork submerged overflow more likely than May be more water.

Brass cube, its volume of water Its not a lump of water displacing, will sink. Beaker of water spill out, so just 8 ML (8cm ^ 3) of the. Coke floats, So it's a group of water itself displaces - Like you said, 8.8 ML is. (Why the difference? Floating body weight of the water itself, but not completely submerged One displaces its own volume displaces. Think about it - the brass than gold cube If more weight, but they occupy the same volume, Gold Brass cube, and then still only the same volume of water displaces. 0.5 g / cm ^ 3, but the density of the wood (5x4x2 cm) pieces, will be floating Lower than the cork in water, the more water you want to replace).

Scientists analyze structural changes in calcium channels caused by Timothy-mutation
The human genome encodes 243 voltage-gated ion channels. Mutations in calcium channels can cause severe inherited diseases such as migraine, night blindness, autism spectrum disorders and Timothy syndrome, which leads to severe cardiovascular disorders.
