The potential energy of a molecule increases when it is brought to the...
Explanation:
When a molecule is brought to the surface from the interior of a liquid, its potential energy increases. The reason for this is:
Work has to be done to move a molecule to the surface against the attraction from other molecules
The molecules in a liquid are held together by intermolecular forces, such as van der Waals forces, hydrogen bonding, and dipole-dipole interactions. These forces attract the molecules to each other and create a cohesive force that holds the liquid together. As a result, it takes work to move a molecule from the interior of the liquid to the surface. This work is done against the cohesive force of the liquid, which requires energy to overcome.
Therefore, the potential energy of a molecule increases when it is brought to the surface from the interior of a liquid because work has to be done to move the molecule to the surface against the attraction from other molecules.
Other options can be eliminated because:
- At the free liquid surface gravitational potential energy is more: Gravitational potential energy is not relevant in this context as it's not the force that is being overcome to move the molecule to the surface.
- The temperature of the liquid surface is always more than that of the interior of the liquid: Temperature is not relevant in this context as it does not affect the potential energy of the molecule.
- Work has to be done to move a molecule to the surface against the repulsive component of the intermolecular forces: This option is incorrect as intermolecular forces are attractive, not repulsive.
