Type: MCQ-diagram based-Easy-Class 11
Consider a diagram showing molecules in a liquid at the surface and inside the bulk. Which statement correctly describes the potential energy of a molecule near the surface compared to one fully inside?
A
A molecule at the surface has more potential energy than one inside.
B
A molecule at the surface has less potential energy than one inside.
C
Both molecules have the same potential energy.
D
Potential energy is irrelevant for molecules in a liquid.
Correct Answer
Option A
Detailed Explanation
The NCERT context states that molecules on a liquid surface have extra energy compared to those in the interior, due to fewer surrounding molecules.
