What is happening to the particles of water in ice as it turns to liquid using the particle model of matter?

As ice melts into liquid water, the particles that make up the ice, which are arranged in a rigid, orderly structure, gain energy from heat. This increase in energy causes the particles to vibrate more vigorously, breaking the bonds that hold them in place. Consequently, the particles move closer together but can slide past one another, leading to the formation of liquid water. This transition demonstrates the change from a solid state, characterized by fixed positions of particles, to a liquid state, where particles have greater freedom of movement.
