What is the measure of metallic bond strength?
What is the measure of metallic bond strength? The amount of energy as heat required to vaporize the metal is a measure of the strength of the bonds that hold the metal together. The enthalpy of vaporization is defined as the amount of energy absorbed as heat when a specified amount of substance vaporizes at […]

Which way is the South American plate moving?
Which way is the South American plate moving? Geological research suggests that the South American Plate is moving westward away from the Mid-Atlantic Ridge: “Parts of the plate boundaries consisting of alternations of relatively short transform fault and spreading ridge segments are represented by a boundary following the general trend.” As a result, the eastward […]
