imagine a snowflake in your hand, and you look at it, and it's an incredibly complicated, beautiful object. But as you heat it up, it'll melt into a pool of water, and you would be able to see that, actually, it was just made of H20, water.
iedomājieties sniegpārslu uz plaukstas, un jūs uz to skatāties, un tā ir neticami sarežģīts, skaists objekts. Bet jūs to sasildāt, tā izkūst ūdens lāsē, un jūs varat redzēt, ka patiesībā tā sastāv tikai no H2O, no ūdens.
