Phase changes of a water molecule.

Hi, I am Bozzly, the water corpuscle. Join me with my band of molecule friends as we experience the shape trades of water into the actually cupful of lemonade you are holding right now. The first amazing phase change volition transform us into a liquid. right-hand(a) now my friends and I are tightly bonded together and cannot ply around very much. Can you spot us? I think you watch. We are the thick rubbish cubes that are at the bottom of your empty cup. I guess you liked the lemonade very much! Now going from a solid to a liquid requires heat energy, which will result in melting. Since it is a hot day outside the heat is able to get by the solid bonds in the meth. Watch blottoly as we ice molecules start to melt. This is because the ice is buy uping the heat energy. The bonds of the solid ice are slowly breaking down and soon we molecules compose free to flow and move around. Now that our ice molecules move over warmed, being a liquid is quite nice. We liquid molecules are free to move around, but my friends and I remain close by each other.

Now that my friends and I are a liquid, we will miraculously change into the next phase: a gas. If you have the time, you can see this happen.

Set the cup you are holding right now on the table and pull up a chair to watch this scientific process. For us to change into a gas, we liquid water molecules must vaporize. During this process, we must absorb heat energy to escape from the liquid phase. Changes in temperature affects the prise that it takes us water molecules to absorb heat in pronounce to evaporate. Since it is a hot day...
