the molecules vibrate, faster and faster as the heat increases then they become disordered
When a solid is melted, the molecules gain enough energy to overcome the forces holding them together in a rigid structure. As a result, the molecules move more freely and take on a more disordered arrangement, transitioning from a solid to a liquid state.

When heat is added to a substance, the molecules and atoms vibrate faster.
Nothing. Melting is a physical change and does not alter the chemical composition of a substance.

Nothing. Hydrogen bonds are very strong. When ice is melted, only weak intermolecular forces of attraction that exist between H2O molecules will be broken.
As a substance melts, the molecules of the formerly-solid substance becomes less structured and drifts further apart.
they spread apart and move faster when energy is added.
When ice melts, the ice molecules gain energy from their surroundings and their bonds weaken. This causes the molecules to vibrate more and move further apart, transitioning from a solid state to a liquid state.
