during melting, the forces of attraction between the molecules\na become weaker.\nb remain the same.\nc become stronger.\nd become stronger and then weaker.
Answer
Brief Explanations:
Melting is a phase - change process where a solid turns into a liquid. In a solid, molecules are closely packed due to strong intermolecular forces. As heat is added during melting, the kinetic energy of the molecules increases and they start to move more freely. This implies that the intermolecular forces of attraction between the molecules become weaker to allow the change from a more ordered (solid) to a less - ordered (liquid) state.
Answer:
A. become weaker
