* Increased Kinetic Energy: The heat energy absorbed by the ice cubes causes the water molecules (H₂O) to vibrate and move faster. This increased motion is called increased kinetic energy.
* Breaking of Hydrogen Bonds: Ice is held together by strong hydrogen bonds between the water molecules. As the temperature increases, the kinetic energy of the molecules overcomes these bonds. The bonds start to break, causing the ice to lose its rigid structure.
* Phase Transition: As the bonds break, the molecules start to move more freely, transitioning from a solid (ice) to a liquid (water). This is the melting process.
* Increased Spacing: In the liquid state, the water molecules have more space to move around than in the solid state. This increased spacing is what makes liquid water more fluid than ice.
In summary, heating ice cubes causes the constituent atoms to move faster, break their bonds, transition into a liquid state, and occupy more space.
