Classification of discontinuities in metal processing involves identifying interruptions in the normal physical structure, such as cracks, seams, and inclusions, which may or may not be defects. Discontinuities can be surface or subsurface, with surface ones being more likely harmful. The origins of

Water molecules exhibit different behaviors in the liquid and gaseous states due to varying attractions between molecules. To change liquid water to a gas, energy must be added to overcome intermolecular forces, making this process endothermic. The heat absorbed during melting is equal to the heat r
