A blacksmith strikes a piece of metal with a hammer repeatedly. The metal slowly begins to glow as the temperature increases, and the metal becomes more malleable. Which changes on a microscopic level led to the visible changes in the properties of the metal?
increased, causing them to vibrate more rapidly. This increase in temperature caused the atoms and molecules within the metal to have more kinetic energy, leading to increased collisions and interactions between them. As a result, the metal's internal structure and arrangement were disrupted, causing dislocations within the crystal lattice. These dislocations make it easier for the metal to deform and change shape, making it more malleable. Additionally, the increased temperature also caused the atoms and molecules to emit more thermal radiation, leading to the metal glowing.
