You heat a piece of iron from 200 K to 400 K. What happens to the energy of random motion of the atoms?

When you heat a piece of iron from 200 degree Kelvin to 400 degree Kelvin, then the kinetic energy of the molecules increases and so they start travelling faster at a random motion. Whenever the temperature of any object increases the atoms and molecules present within the object start moving faster as they are boosted by additional kinetic energy. Under normal circumstances the particles of the iron are held together in an orderly fashion and with increased heat, this orderliness starts dissipating as the particles gain in energy and start moving faster randomly.

When you heat a piece of iron from 200 K to 400 K, the energy of random motion of the atoms increases. Heat is a form of kinetic energy, which is the energy possessed by objects due to their motion. According to kinetic theory, this means that as the temperature of the iron increases, the kinetic energy of the iron atoms also increases, causing them to move more vigorously. The iron's temperature is a measure of the average kinetic energy of its atoms. Thus, when the iron is heated, the average kinetic energy of its atoms increases, leading to a higher degree of random motion.

Heating iron from 200 K to 400 K increases the kinetic energy of its atoms, causing them to vibrate and move more rapidly. This increase in energy results in a state of greater random motion among the atoms. Consequently, the orderly arrangement begins to dissipate due to the added thermal energy.
