Ice melting and evaporating
Videonummer 11919771
| Animation of ice melting into liquid water, and then turning into vapour. At the start, the ice exists in a regular hexagonal crystal lattice, with the hydrogen atoms (white) on each water molecule forming hydrogen bonds (blue lines) with an adjacent oxygen atom. This regular arrangement makes ice occupy a larger volume than liquid water. After a pulse of heat (red), the lattice breaks down, as the molecules gain enough energy to disrupt the hydrogen bonding, forming liquid water. After another pulse of heat, the molecules gain enough energy to leave the liquid state altogether, escaping as water vapour, a process called evaporation. | |
