Explanation for correct option: (B)
Condensation:
- The process by which the physical state of matter transitions from gaseous to liquid is known as condensation.
- Condensation occurs when water vapor in the air comes into contact with a cooler surface.
- The attractions and interactions between water molecules are dealt with in the bond-breaking and bond-forming processes involved in evaporation and condensation.
- Kinetic energy is the energy that atoms and molecules have as a result of their motion.
- Potential energy is the energy they have as a result of their attraction to each other.
- When we say that breaking bonds requires energy and forming bonds requires energy, we really mean that energy is transferred between kinetic and potential energy.
- Separating two water molecules, for example, necessitates a certain amount of kinetic energy.
- The kinetic energy utilized to separate them is transformed into the potential energy of attraction between them when they are separated.
- This potential energy is transformed back to kinetic energy if they come together again.
- Energy is transformed from one form to another, not created or destroyed.
- On cooling, the gas molecules lose heat energy which decreases the kinetic energy as well as the potential energy of the molecules.
- Further extraction of heat results in a decrease in the potential energy of molecules, whereas kinetic energy remains constant.
- And; a decrease in potential energy leads to an increase in intermolecular forces of attraction.
- An increase in the forces of attraction results in the conversion of state.
Thus, according to the above explanation; the arrangement of steps of the condensation process is as follows; BADC
Conclusion: The correct option is (B).
