Answer: Option (A) is the correct answer.
Step-by-step explanation:
When a gas is heated then its molecules gain more amount of kinetic energy. And, as kinetic energy is the energy obtained by an object due to its motion.
Therefore, with increase in kinetic energy of molecules of the gas there will occur more number of collisions. Hence, the gas will move more rapidly from one place to another.
Therefore, upon heating of a gas the energy absorbed by the gas will get converted into kinetic energy due to which gas move much more rapidly.
Potential energy is the energy obtained by an object due to its position and not because of its movement.
Thus, we can conclude that when a gas is heated all of the absorbed energy is converted to kinetic energy.
