Inside of Venus. Venus is a rocky planet, much like the Earth. Given its similar size, mass, and density to our planet, scientists think that its interior is much like Earth's own. In addition to a crust significantly older than Earth's constantly changing surface, Venus likely also sports a mantle and a core.
From Wikipedia, the free encyclopedia. The hematocrit (Ht or HCT, British English spelling haematocrit), also known as packed cell volume (PCV) or erythrocyte volume fraction (EVF), is the volume percentage (%) of red blood cells in blood. It is normally 45% for men and 40% for women.rom Wikipedia, the free encyclopedia.

Calculate the amount of heat needed to raise the temperature of a baseball-sized hunk of sodium metal (225 grams) from 20.oC (room temperature) to its melting point of 98oC. (The heat capacity of solid sodium metal is 0.293 cal/goC.) heat = mCDT = 225 g (0.293 cal/goC) (98oC â 20oC) = 5100 cal or 5.1 kcal.
